tricky one here!

A. processes; nanoflowers may, for instance, serve - CORRECT
B. processes; which might, as an instance, be the serving - Which refers to the wrong word
C. processes, as an instance, to serve - As an instance is wordy
D. processes, like to serve - like to serve is wordy and not correct
E. processes, such as to be serving - to be serving is wrong

Hope its clear!

I tried to explain it in another way, by looking at the meaning of the sentence but it will be to complicated. This way is the simpliest one!

Official Explanation

- The proper idiomatic use of the word "instance" when indicating an example, is "for instance", not "as an instance". Therefore, a vertical scan allows us to eliminate (B) and (C).

(E) would require "such as by serving" to be correct, so we eliminate (E).

(D) incorrectly uses "like" to introduce an example; "such as" - or, less commonly, "for instance" or "for example" - should always be used to introduce an example. Therefore, we eliminate (D) and are left with choice (A), the correct answer.

if, 'as to be serving' is omitted from E, will it be a better choice?
