The correct answer is option b. "writ of habeas corpus".
Explanation:
Habeas corpus is a recourse in law that could be exercised to demand an explanation of why an officer holds a prisoner, which implies that the person using it is reporting an unlawful detention or imprisonment. The process to follow is that a court order demands that the officer presents the prisoner in court, and the officer must present proof of authority in order to keep the person in detention.
