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

(B) for attracting females rises and falls in accordance with the surrounding temperature, which can in fact serve

(C) in attracting females rise and fall in accordance with the surrounding temperature, in fact possibly serving

(D) to attract females rises and falls in accordance with the surrounding temperature, and it can in fact serve

(E) to attract females rises and falls in accordance with the surrounding temperature, in fact possibly serving

我的问题是D选项中“and it can in fact serve"中的”it"是否会造成指代歧义，即it 就近指代temperature?    有劳大家帮忙解惑，谢谢！

不会，and连接两个句子，二句中的it优先指代一句中与其作用相同的成分——即一句中的主语the number of chirps
