Hi Mohammad,

As Ron notes in this Manhattan thread:

https://www.manhattanprep.com/gmat/forums/because-there-are-provisions-t7381-75.html

If you have noun + , + __ing, then the __ing describes that initial noun. I.e., if there are other nouns in modifier(s) attached to that noun, then comma + __ing DOES NOT describe those closer nouns.


Thus, "having hundreds of miniature eyes" refers to "The intricate structure." That's not correct. It should refer to "the compound insect eye." It's not the structure that has eyes; it's the compound eye itself.

We can make a split:
A, B, C - contain "having" participle at the beginning of the underlined sentence. The subject "structure" needs a verb, therefore choices A,B,C -can be eliminated.
Between D & E we should choose singular verb "helps". So the answer is E
