Why is misuse of government machinery in elections wrong?

Correct answer: Because it may give unfair advantage to a party

Government machinery includes public offices, officials, vehicles, money, facilities, and administrative authority. During an election, these resources are meant to serve the public and administer the election impartially, not to help one party or candidate. If a ruling party uses government staff, public funds, official buildings, or state power for partisan campaigning, it can gain an unfair advantage and weaken equal competition.

The other choices describe unrelated or impossible effects. Misuse of machinery does not clean polling booths, correct the voter list, or make electronic voting machines new. The central concern is fairness: public resources must not be converted into private political advantage. This is why option A is correct. Preventing such misuse supports free and fair elections and helps voters judge candidates without coercion or an artificially unequal campaign environment.
