Dear
Vyshak,
I'm happy to respond.

This is not a high quality question.
Split #1: the construction "
try and [verb]" is an American colloquial construction that is grammatically incorrect. Eliminate (A) & (B). It really overkill having two answer choices with this mistake.
Now, the three remaining choices
(C) looks good: direct and powerful
(D) is incredibly awkward, and has the strange passive construction; this is wrong.
(E) this also phrases things in an indirect passive way; this is wrong.
Vyshak, did you post the correct OA? It's beyond me how anyone who knows anything about the GMAT SC could say that (E) is right and (C) is wrong. Something is off here. Even aside from this, this is not a well-constructed question.
Here's a high quality GMAT SC practice question:
What the eye seesDoes all this make sense?
