In some species of cricket, the number of chirps per minute used by the male for attracting females rise and fall in accordance with the surrounding temperature, and they can in fact serve as an approximate thermometer.

A. for attracting females rise and fall in accordance with the surrounding temperature, and they can in fact serve.
The number is singular so it does not agree with plural "rise" and "fall".

B. for attracting females rises and falls in accordance with the surrounding temperature, which can in fact serve
"which" is referring to temperature. Moreover "used...for attracting" is not the correct usage.

C. in attracting females rise and fall in accordance with the surrounding temperature, in fact possibly serving.
The number is singular so it does not agree with plural "rise" and "fall".

D. to attract females rises and falls in accordance with the surrounding temperature, and it can in fact serve.
"It" does not have a clear referrent, "cricket or chirps".

E. to attract females rises and falls in accordance with the surrounding temperature, in fact possibly serving.
This is proper case of subordination.

The correct form to say is used...to do sth. So eliminate A, B, and C.
The it in D is unclear on what it is referring to.

D vs E.
As much as I dont like the phrase "in fact possibly" in E, E still nudges D out.

D because E change the meaning of the original sentence (in addition to being awkward)

can serve vs possibly serve

D would be the better choice since "and it can in fact serve" is more appropriate

That is why non official questions are not useful, and often create more confusion than they are worth.

Here number of chirps is referred to and number is a singular noun. so B is not appropriate. i will go for D.

"the number of chirps per minute" is singular and so must be modified by "rises" and not "rise"

A) Incorrect - uses "rise" and not "rises"
B) Incorrect - ", which" is used to modify the noun directly in front of the comma. In this case that word is "temperature", but it should be referring to "number of chirps"
C) Incorrect - uses "rise" and not "rises"
D) Incorrect - "and it can in fact" is an ambiguous pronoun. "it" can refer to the number of chirps or the temperature.
E) Correct - uses "rises" correctly. Also, the construction of COMMA + -ING VERB can be used to construct a modifier phrase that modifies the entire clause proceeding it. In this case, "in fact possibly SERVING" is used to modify the entire modifier phrase starting with "used by...".

The COMMA + -ING VERB is a fairly common occurrence in the GMAT, and one that you should be on the lookout for.

For example:

"Crime was reduced in the neighborhood, which caused property values to rise." (INCORRECT)
", which" can only modify the noun directly in front of the comma. So in this case, it should be modifying "neighborhood". However, the neighborhood has not caused property values to rise.

Correct ways to fix this:

1. Make it so that the modifier correctly references "neighborhood".
"Crime was reduced in the neighborhood, which experienced higher property values." (Correct)

2. An -ing verb, unlike ", which" can be used to modify the entire phrase before it.
"Crime was reduced in the neighborhood, causing property values to rise." (Correct)

IMO normally, unless a idiom requires the use of FOR or TO, you use TO to express intend or objective
Consider the following example

I used the product FOR cleaning the motorcycle TO clean the car

The first part of the sentence uses FOR because the product is designed for cleaning motorcycles; however, if you are using the product in this particular case with the intention to clean the car, you use TO.

I don't know whether this is clear for you. My explanation is not really good, I hope someone can provide a better one.

IMO anyway for this problem you don't need to know this differences. I've noticed that sometimes GMAT uses this trick splitting answer choices that seem to test a concept (idiom), while you can eliminate part of the choices using other rules.

I think possibly & in fact can't come together...both are contradictory to each other...

In fact : in reality

This is actually an official question from GMATPrep.

Could anybody explain why "it" in D is not ambiguous?

And aside from that: whats wrong with B and E?
Thanks.
