Why is action against a candidate who breaks election rules necessary?

Correct answer: To maintain fairness

Direct answer: A is correct. Election rules create common conditions for all candidates and parties. If a candidate uses bribery, intimidation, prohibited campaigning, false practices, or another violation, that candidate may gain an unfair advantage and voters may not be able to choose freely. Action by the appropriate election authority can stop the violation, impose the permitted consequence, and protect equal competition. B is unrelated because voting age is governed by law, not by punishment for one candidate. C is not the general purpose of enforcement; an election symbol is part of the electoral process and cannot simply be erased as a routine response. D has no connection with election rules. The larger principle is accountability: fair competition requires both rules and meaningful action when rules are broken. Memory cue: rules without enforcement cannot protect fairness.
