Correct answer: A. Fair hearing
Explanation: Direct answer: Option A, fair hearing. A fair hearing means that before a person is declared guilty or punished, the decision-maker listens to that person’s explanation and considers the relevant facts. The reasoning is: an accusation is only a claim; it is not automatically proof. The accused student must know the charge, get a real chance to respond, and be judged through a fair process. This reduces mistakes and prevents one-sided or biased decisions. Option A is correct because it directly describes hearing both sides. Option B, election campaign, is activity used to seek votes and has no connection with deciding a student’s guilt. Option C, voter list, records eligible voters and is irrelevant here. Option D, tax payment, concerns citizens’ financial obligations, not disciplinary fairness. Memory cue: before punishment, hear the person’s side.
