B is not correct because the subject of the first part is "color-discriminating apparatus" and not "human eye"
D compares correctly and hence the ans IMO

i agree with D. in order to compare apples and apples, you have to compare apparatus of a human eye to apparatus of an insect eye.

The first segment of the statement mentions the color-discriminating apparatus of the human eye. So, the second segment should also mention a part of the insects' eye. Only then would the comparison be appropriate. In B, you will be comparing avocado seeds to avocadoes  "that of an insect's eye" correctly compares the color-discriminating apparatuses. Hence D is correct-Anand

Like the color-discriminating apparatus of the human eye, insects’ eyes depend on recording and comparing light intensities in three regions of the electromagnetic spectrum. (A) insects’ eyes depend on -> compare apparatus of human eye with that of insects' and not insects' eye itself.-> eliminate (B) an insect eye depends on -> eliminate -> same reason as above (C) that of insects depend on the -> the is misleading .Apparatus of insect eyes and not insects.eliminate (D) that of an insect’s eye depends on ->CORRECT (E) that of an insect’s is dependent on the -> the is misleadig again.eliminate IMO (D) answer please .........

Original sentence has following issues
1) comparing apparatus with insects' eyes
2) depend is plural but the verb required is singular
D corrects both these problems

(A) insects’ eyes depend on - wrong comparison
(B) an insect eye depends on - wrong comparison
(C) that of insects depend on the - 'insects' what???
(D) that [the color-discriminating apparatus] of an insect’s eye depends on - correct
(E) that of an insect’s is dependent on the - 'insects's' what???

But in the problem at hand we are essentially saying the color-discriminating apparatus of eye of the insect. (insect's is modifying eye). The following usage would be incorrect: that of the eye'sCrick
