If an official uses law for private revenge what is the problem?

Correct answer: Misuse of public power

Direct answer: C, misuse of public power. An official receives authority to perform a public duty, not to settle a personal quarrel. Reasoning: first, the official uses government position, law or state machinery; second, the real purpose is private revenge; third, public authority is therefore diverted from lawful public service. This is abuse of power and may also violate fairness and rights. Option A, tax policy, concerns government decisions about taxation and is not the central wrong. Option B, election symbol, concerns identifying political parties and has no connection with revenge through office. Option C is correct because power belonging to the public is being used for a private motive. Option D, voting secrecy, concerns keeping a voter’s choice confidential, which is a different issue. Officials must act according to law, relevant reasons and public interest, not anger or personal benefit. Memory cue: public office means public purpose, not private revenge.
