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.

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

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.
