OFFICIAL EXPLANATION
• Split #1: affects vs. effects
We have a 3-2 split, one that even native speakers have a hard time with. (In terms of difficulty, the affect/effect split is right up there with between you and I and between you and me. The second phrase is correct.)
The word in question should be a noun.
Eliminating mosquitoes could have a bad result. A result is a noun.
Eliminating mosquitoes could have serious ecological effects.
Almost always, the word effects with an "e" is a noun.
Almost always, the word affects with an "a" is a verb.
Options A, B, and C incorrectly use the verb affects.
Eliminate A, B, and C
I have seen a few mnemonics to help you remember the difference between the two words.
Think: Affect starts with an A and is an Action (a verb),
whereas Effect starts with an E and is an
End-result (a noun)
(Yes, I know that the mnemonic is corny. I also know that it works.)
• Split #3: option D contains a few errors
• The gerund eliminating is better than the infinitive to eliminate (that situation is almost entirely idiomatic -- don't worry too much about it because other errors in D are worse)
• The verb can in options D and B is not nearly as good a choice as "could have" in the other options.
-- Remember to pay attention to the nonunderlined portion.
The words scientists do not yet understand signal that the sentence describes a hypothetical situation.
Could have (meaning might have) correctly expresses uncertainty.
• they is ambiguous.
-- They could refer to mosquitoes or ecological effects
• finally, compare option D to option E: no contest.
Option E does not contain the same problems as option D does.
Eliminate D
The best answer is E.
• including the noun mosquitoes avoids the problems with they
• could have is more accurate than can. The situation is hypothetical, so we need a could (might), not a can.

The answer should be E because there is a point of difference :effect and affect. We will go for effect. we are left with d and E. And i would choose E.
