Answer:
C. eccentric ... levity
Explanation:
This is the answer that makes the most sense in the context. In this sentence, we need a word of similar meaning to "odd," because both words are being used to describe the woman's habit. The closest word in meaning is "eccentric." Moreover, the complaint talks about serious discussions being affected by her additions. The correct word in the second blank is "levity," because the word means "frivolousness" or "lightness."
