The correct answer is C. Contradict.
To gainsay is to express the opposite of what someone has said. It means to deny, contradict, or oppose.
Option A, advantage, is the opposite of gainsay. An advantage is something that gives someone a better position or chance of succeeding.

Option D, suggestion, is a proposal or idea that is put forward for consideration. It is not the opposite of gainsay.
Here are some examples of how the word “gainsay” can be used in a sentence:
