Option D appears wrong to me, but it is the OA
In option-D, what does “it” refer to? Is it the cricket, chirps or surrounding temperatures. No such ambiguity exists in Option E. It appears to be just wordy. So which one would you go for as your answer choice, a wordy or a supposedly wrong option.
- 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
