I have a hard time with E on this one.
I understand that "have the most impact" is correct idiom compare to "impact the most on. However, "Is "which" in E correct use?

For example:

I have pen, pencil, and paper, which I used to take notes.

Is "which" correctly used here?

I went with A. then saw Hanumayama's response.

His comment on A seems right.

Confused on this one. C does sound awkward but could be right.
