Q1. Which of the following writs is issued by the Supreme Court to prevent an inferior court from usurping jurisdiction that is not vested in it?
A Mandamus
B Certiorari
C Prohibition Correct
D Habeas Corpus
Explanation
The writ of prohibition is preventive: a superior court issues it to stop a lower court or tribunal from proceeding beyond its lawful jurisdiction. Mandamus commands a public authority to perform a legal duty, so it is not the jurisdiction-stopping writ asked here. Certiorari usually quashes an order already passed without jurisdiction or with legal error, making it corrective rather than primarily preventive. Habeas corpus concerns unlawful detention and production of the detained person before the court.
