周老师解释：Agreement; Logical predication
This sentence addresses why scientists have decided that the vertebrate eye and the insect eye evolved independently of each other. The insect eye is much more intricate, with hundreds of miniature eyes. The sentence needs to be clean as to what has hundreds of miniature eyes. The structure or the insect eye? Furthermore, the singular subject intricate structure requires the singular verb helps.
A.This wording misleadingly suggests that the intricate structure has miniature eyes, while the correct subject of the predicate having is the compound insect eye. Subject-verb agreement is violated.
B.同A; they应该指代the compound insect eye, 所以不能是复数
C.scientists' assuming这种所有格形式unwarranted, verbose and awkward； they应该指代the compound insect eye, 所以不能是复数
D.help主谓不一致；scientists' assuming这种所有格形式unwarranted, verbose and awkward
E.是标准答案。
