hello syamee_u!

I am undecided between (C) and (E)! could you please explain why (E) is preferable towards (C).

(C) ....not only + (verb) + (X) ...but also... (Y)

(E) (verb) ....not only ... (X) ...but also... (Y)

Cheers

A and B are out because of using plural verb. Singular verb is required here.

D is out because of using 'like'. Such as should be used to give examples.

C is NOT parallel.

E is the best answer.

not only (by) X ... but also (by) Y -- parallelism

we need by after 'Not only' as it follows after but also..

So, E is perfect choice.

we need 'such as'. So consider B,C and E.

B uses 'are' for survival, which is wrong.
C attempts to compare a threat with something else. Out.

E is best.

A. are being threatened, experts say, not only by pollutants like

B. are being threatened, experts say, by not only pollutants such as

C. is not only being threatened, experts say, by pollutants such as

D. is not only being threatened, experts say, by pollutants like

E. is being threatened, experts say, not only by pollutants such as

A, B - Eliminate - Subject Verb
C, D - Eliminate - sentence is fragmented.
Correct idiom is not only X but also Y
Hence E is the answer.

for giving examples such as is needed: A and D thus are eliminated.
Survival is - B has verb number error.
in non-underlined portion we have - but also by. Taking this into consideration, we can conclude that "not only by" should be in the underlined portion.
C is out, and E is the correct answer.
