A. objects, which in turn detect
'which' modifies the noun exactly before which and the rules are strict related to which , so this is wrong modificaion case.
B. objects, and they will detect
'They will' is wrong usage of tense because they always detect the objects and thus we should use present tense.
C. objects, resulting in detecting
detecting is modifying the genes and not elephants, and thus wrong diction.
D. objects that result in detecting
use and detecting is not parallel so not a correct answer along with the reason in the option C.
E. objects and thereby detect
Correct and crisp meaning, modification and diction.

E has to be the correct answer.

A. objects, which in turn detect
B. objects, and they will detect
C. objects, resulting in detecting
D. objects that result in detecting
E. objects and thereby detect

A can be eliminated because WHICH refers to objects and objects do not detect odour.
B can be eliminated because THEY could refer to objects as well as elephants.
C can be eliminated because the use of DETECTING is wrong. it should be detection.
D can be eliminated because of same error as A.

Problem with stem post is the usage of 'which', which is modifying objects while actually it should be implying genes. So A is out.
Similar problem with option D.

Option B has an ambigious usage of pronoun 'they'.

Option C contains no verb specifying action.

Hence IMO option E.

the sentence is correct as is. "which correctly refers to genes".

Unlike all the other mammal species whose olfactory receptors, which detect smell, were studied, the African elephants use nearly 2,000 olfactory genes to smell various objects, which in turn detect their odor.

A. objects, which in turn detect
The noun-modifier "which" most directly modifies "objects" in this sentence. This makes it seem like the object is detecting the odor of the olfactory genes. Probably not the intended meaning of the sentence.

B. objects, and they will detect
"Will detect" changes the verb tense from the original unnecessarily.

C. objects, resulting in detecting
"Resulting in detecting" is unnecessarily complicated, changes the Verne tense from the original for no reason.

D. objects that result in detecting
The sentence introduces a gerund, and changes the verb tense from the original without cause. A simpler and more ideal option is available in E.

E. objects and thereby detect
States that the elephants use the receptors to smell and ... detect. The parallel verb structure seems preferable to the structure in D.

Therefore, I think E is the best answer choice here.

A,D - modifier error --> object does not detect odour.

B- the antecedent of "they" is elephant thus distorting the meaning.

C - E is parallel and crisp than C.

Hence, E is the answer.

A. objects, which in turn detect
Modifier error. ''Which" wrongly modifies objects and gives the meaning that objects detect odor - Distorts meaning

B. objects, and they will detect
This suggests that using the receptors and detecting smell are unrelated whereas there is actually a causality here. The usage of receptors enables odor detection.

C. objects, resulting in detecting
"Resulting" wrongly modifies objects - distorts meaning

D. objects that result in detecting
"That" wrongly modifies objects - distorts meaning

E. objects and thereby detect
"Thereby" establishes a causality between usage of receptors and detecting odor.

Answer is (E)

A. objects, which in turn detect which is a wrong modifier here
B. objects, and they will detect will is the incorrect tense
C. objects, resulting in detecting detecting should be a noun "detection"
D. objects that result in detecting illogical and detecting error as above
E. objects and thereby detect correct response

A. objects, which in turn detect - Objects don't deduct the Odor
B. objects, and they will detect - Unclear antecedent for they - Objects, Elephants, or genes
C. objects, resulting in detecting - Incorrect meaning and structure - modifier
D. objects that result in detecting - Objects don't deduct the Odor
E. objects and thereby detect Correct

IMO E

E I think.

A is wrong because objects themselves cant smell, which is what implied by "which"
B starts a new clause, breaking the flow of the sentence
C has wrong modifier, elephants cant be "resulting" in anything
D wrong meaning because of "that" which again refers to "objects" and they cant result in smelling anything.
E looks okay as elephants can smell objects and detect as well.

A. objects, which in turn detect —> wrong as in this case “which” refers to the noun prior to it (objects). However, “objects” cannot detect “odor”, instead, the act of using 2000 olfactory detect the odor.

B. objects, and they will detect —> “they” here is ambiguous as we don’t know if “they” refers to “2000 olfactory” or “various objects” —> wrong.

C. objects, resulting in detecting —> this is good as using present participle V-ing (resulting) can modify the whole clause prededing it (while “which result” can only refer to the noun immediately preceding it) —> correct

D. objects that result in detecting —> wrong for same reasons as A

E. objects and thereby detect —> it should be “thereby detecting...” —> wrong

So the answer is C

A. objects, which in turn detect
'which' incorrectly refers to objects

B. objects, and they will detect
Pronoun 'they' is ambiguous since there is another 'their' that refers to objects

C. objects, resulting in detecting
Correct. 'Resulting in detecting' modifies the preceding clause.

D. objects that result in detecting
'that' indicates the clause following it modifies objects which is incorrect.

E. objects and thereby detect
The separate clause 'thereby detect...' is parallel to 'elephants use A and thereby B' which implies the pronoun 'their' would refer 'elephants' which is incorrect as 'their' should refer to various objects.

Option C

A. objects, which in turn detect
Which here refers to objects and hence is incorrect.

B. objects, and they will detect
They here are ambiguous, it could refer to genes, objects or African elephants

C. objects, resulting in detecting
This shows a cause and effect stating that African elephants use nearly 2,000 olfactory genes to smell various objects, "effect of which" results in detecting..., incorrect.

D. objects that result in detecting
This again refers to objects which are incorrect.

E. objects and thereby detect
This is the correct version, concise and precise.

The answer is E.

A. objects, which in turn detect: this is a proper phrase, in turn, means something works successively.
B. objects and they will detect: this seems to correct but does not relate to there olfactory genes, which the statement talks about. And comma should not be used.
C. objects, resulting in detecting: Unnecessary use of gerund (+ing). Does not work with proper structure.
D. objects that result in detecting: detecting is gerund format, should be omitted.
E. objects and thereby detect: It also looks fine but does not relate to olfactory genes.

IMO the answer is A.

A. objects, which in turn detect - which refers to objects. WRONG
B. objects, and they will detect - They can refer to receptors and objects. Wrong
C. objects, resulting in detecting - WRONG
D. objects that result in detecting - Meaning error. Objects don't result in detecting anything.
E. objects and thereby detect - CORRECT

A. objects, which in turn detect - which correctly refers to olfactory genes. CORRECT
B. objects, and theywill detect - they refers to elephant. So, it changes the meaning. As if elephant detect odor.
C. objects, resulting in detecting - use of Verb-ing modifier is incorrect.
D. objects that result in detecting - use of that is again incorrect. because it refers back to object. Object detect odor meaningless.
E. objects and thereby detect . This also changes the meaning. As if elephant detect odor

IMO A.

A. objects, which in turn detect - Incorrect; leads to "object detect"
B. objects, and they will detect - Incorrect; we could think that "elephants will detect" or "object will detect"
C. objects, resulting in detecting - Incorrect; parallelism doesn't work here (use...resulting)
D. objects that result in detecting - Incorrect; parallelism doesn't work here (use... that result in)
E. objects and thereby detect - Correct; Parallelism: use and detect
