C. His innocence to him, in a confused way, was impossible to prove, as his sharpness was known.
Explanation:
A. is not the correct answer. This line only says who was on the square and paints the scene better.
B. is not the correct answer. This line talks about the smell and is a description of the atmosphere in the story.
C. is the correct answer. In this sentence, we can see how silly it is for the character mentioned to pretend to be confused and clueless about the happenings since he is known for having a sharp wit. Therefore it supports the central theme.
