The tip to pick a correct answer is to see the non-underlined part "when it is not". Technically, the correct structure should be "X is abc....when it is not abc.....", ("abc" is adjective). Two parts (before and after "when") should be parallel.

The defective thermometers will sometimes fail to register a fever when it is present and indicate that there is one when it is not.

a fever when it is present and indicate that there is one
Wrong. "There is one when it is not" is not parallel.

a fever when it is present and indicate that one is present
Correct. "one is present when it is not [present]" ==> Parallelism. (subject + is + adj when subject + is not [+ adj])

when a fever is present and indicate that there is one
Wrong. Same as A.

when a fever is present and indicates its presence
Wrong. "its present when it is not" ==> not parallel (noun vs clause)

the presence of a fever when it is there and indicates its presence
Wrong. Same as D. "its present when it is not" ==> not parallel (noun vs clause)

Hope it helps.

IMO, B.

C and D changes the meaning.

I think it's B too.

a) wordy
b)
c) that there is one sounds strange
d) it shouldn't fail to register the time (WHEN...)...changes meaning of orginal sentence
e) very wordy

D, E are obviously out because of simple subject verb agreement issue..

out of A,B,C.. B maintains the parallelism the best..

Hi,

I am waiting for the final answer.

In my opinion, E could be the answer.

Though it is wordy, the usage is good.

when a fever is present and indicate that there is one
when a fever is present and indicates its presence
the presence of a fever when it is there and indicates its presence

Between A and B, I chose B because it has less number of pronouns.

verb 'present' is needed to make proper parallel construction , therefore 'B' is correct.

Can you explain this part little more elaborately.It will be of immense help dude
fever is present(clause)
Indicates(verb)+ its presence(noun)= clause
SO both the sides clauses are only there.SO please point me out where my understanding is going wrong

pqhai's method is WAY too complicated and not correct
Wrong. "There is one when it is not" is not parallel. "when" is NOT a parallelism marker
Maybe I can give you an easier one

The defective thermometers will sometimes fail to register a fever when it is present and indicate that there is one when it is not.

register "a fever when" or "when a fever"? The latter changes the meaning, the correct construct is "register (what?) a fever when(-refer to fever-)", if you change the position of "when" it will refer to the verb and not to the fever itself.
C and D are out.
E is out because of subj-verb agreement

a fever when it is present and indicate that there is one
a fever when it is present and indicate that one[a fever] is present<==parallel, hence correct. "and" is a parallelism marker

I chose B

discarded A and C for " there is one when it is not" - "when it is not" should be preceded by "that one is ___"
discarded D for almost the same reason
