Answer:
The answer is C. Condolence.
Step-by-step explanation:
C is the answer because the word Condolence is actually a verb meaning expressing sympathy to somebody, but that's not the point, the point is that the suffix is "ence" and without the suffix, you get "Condole". I can understand if you got confused with "Plutocracy", but A and B have no suffix because that's their actual word without the suffix.
