clear loud voice, make sure you are aware of the intent behind your voice - is it to persuade (loud projecting booming persuasive), create sympathy (quiet, urging) etc etc.
I think it would be D
Hope this helps!

A pedant is a person who is a perfectionist and just obnoxiously meticulous, specifically with language or academics. The proper word to use for selection A. would be pedestrian, which means a person walking along a road.
