The correct answer is option 1: Habeas Corpus. When a person is unlawfully detained or imprisoned, the court can issue a Habeas Corpus writ. This Latin term translates to "you may have the body" and is a legal action that allows individuals to challenge the legality of their detention. The purpose of a Habeas Corpus writ is to protect the rights and liberty of individuals by ensuring that they are not illegally or unjustly held by the government or any other authority.

Option 2, Mandamus, refers to a court order that commands a public official or government entity to perform a specific duty. Option 3, Certiorari, is a writ issued by a higher court to review the decision of a lower court. Option 4, Quo Warranto, is a legal action taken to challenge a person`s right to hold a public office.
