The correct answer is option 2, Mandamus. Mandamus is a writ that can only be filed against a person holding a public office. It is a legal remedy that orders a public official to perform a duty that they are legally obligated to carry out. The purpose of mandamus is to ensure that government officials and agencies fulfill their duties and responsibilities. It is typically sought when an individual or organization believes that they have been unlawfully denied a right or benefit that they are entitled to by law. This writ is not applicable to individuals outside of public office. Habeas corpus (option 1) is a writ that protects against unlawful detention or imprisonment, and it can be filed against any person or entity holding someone against their will. Prohibition (option 3) and certiorari (option 4) are writs that can be used to challenge the decisions or actions of lower courts or tribunals, and they are not limited to public officials.
