Explanation:

Option A: If a body has been detained unlawfully, the court has the right to instruct the executive authority to present the body.

Option B: Mandamus is a command issued by the court to a public official asking him to perform his official duties that he has failed or refused to perform. It can also be issued against any public body, a corporation, an inferior court, a tribunal or government for the same purpose.

Option C: It is used to prevent usurpation of public offices by ineligible individuals, it can be issued against ineligible executive authorities as well.

Option D: It is issued by a higher court to a lower court or tribunal to prevent the latter from exceeding its jurisdiction or usurping a jurisdiction that it does not possess. Thus, unlike mandamus that directs activity, the prohibition directs inactivity.
