Hydrocarbons, with which fruit flies perfume themselves in species-specific blends, are known to be important in courtship, and apparently this assists flies that taste the hydrocarbons on prospective mates to distinguish their own species from that of others.
A. and apparently this assists flies that taste the hydrocarbons on prospective mates to distinguish their own species from that of
The 'this' is ambiguous and needs a noun immediately following it so we know what 'this' refers to. Also, 'own species from that of' is confusing. What does 'that' stand for? Should simply be 'their own species from other species', or using ellipsis, 'their own species from others.'
B. and apparently this assists flies when they taste the hydrocarbons on prospective mates in distinguishing their own species from those of
Same issue as (A).
C. which apparently assists flies that tastes the hydrocarbons on prospective mates in being able to distinguish their own species from
The use of 'which' incorrectly modifies 'courtship.' Also, 'in being able to...' is wordy.
D. apparently assisting flies to taste the hydrocarbons on prospective mates to distinguish their own species from those of
The idiom is 'assisting in Verb-ing'. Here it is 'assisting...to taste.'
E. apparently assisting flies that taste the hydrocarbons on prospective mates in distinguishing their own species from
Use the correct idiom, 'assisting...in distinguishing.' Also, correctly compares species to species.

(A) and apparently this assists flies that taste the hydrocarbons on prospective mates to distinguish their own species from that of Flies does not agree with that.
(B) and apparently this assists flies when they taste the hydrocarbons on prospective mates in distinguishing their own species from those of "when" is unnecessarily used. It should refer to time.
(C) which apparently assists flies that taste the hydrocarbons on prospective mates in being able to distinguish their own species from "which" refers to "courtship".
(D) apparently assisting flies to taste the hydrocarbons on prospective mates to distinguish their own species from those of "seems ok"
(E) apparently assisting flies that taste the hydrocarbons on prospective mates in distinguishing their own species from Flies do not agree with that. Comparing species with flies.

distinguish their own species from others [species] idiom: distinguish X from Y
distinguish their own species from those/that of other[species] ---> THOSE/THAT refers to what? A,B,D are out C --out WHICH incorrectly refers to courtship.
E is my answer

Problem with D is "assisting flies to taste". This phrase changes the meaning of the whole sentence. The hydrocarbons assists in distinguishing the species and not assists in tasting which actually D mentions. E correctly mentions "assisting flies that taste the hydrocarbons.... in distinguishing....."

(D) apparently assisting flies to taste the hydrocarbons on prospective mates to distinguish their own species from those of
It seems to be conveying that purpose of assistance is "to taste the hydrocarbons", which is definitely not the intended meaning.

So, to refer back to species we need "THAT"

Hi,
I think ellipsis has come to play in choice E or else it would be redundant.
apparently assisting flies that taste the hydrocarbons on prospective mates in distinguishing their own species from others [' species]

I worked hard to spend many hours for the GMAT preparation
or I worked hard, spending hours for the GMAT preparation.
In the first sentence, to spend hours- is not my intention or purpose
In the second sentence, spending hours is the consequence of the hard work
So choice D is wrong for that reason choice D says, hydrocarbon assisting flies to taste
the meaning of the sentence is hydrocarbon assist flies that taste it in distinguishing their species from others (species) 'those of others' has an issue; it should just be 'others' - it's clear that the intention is to refer to other species, not to something of other species).
