'Ad hominem' is demonstrated as the logical fallacy in which the opposite claim is countered by attacking the speaker's character instead of logically countering the arguments. These attacks are irrelevant yet insignificant to the argument as they are based on emotions of prejudice and meant instead of facts, reason, or logic.
In the given example, 'ad hominem' fallacy is being displayed as it attacks Jalessa's character('caught sneaking candy into a movie theater') to undermine her participation and probability of being selected as the 'senior class president' instead of logically and significantly countering her claims(through factual and reasonable counterclaims). Thus, <u>option C</u> is the correct answer.
