Answer:
A. Ad hominem
Explanation:
In Latin, Ad hominem means ‘to the man.’ It is a logical fallacy that attempts to win an argument by undermining or insulting an opponent instead of focusing on the subject of the discussion or on disproving the soundness of what the opponent is actually saying. This fallacy often looks to deviate people's attention from the subject of discussion, and prove that since the opponent has such despicable characteristics, then what he or she is saying is not valid or unworthy of attention.
