Which institution has the power to issue writs?

Correct answer: High Courts and the Supreme Court

The correct answer is the High Courts and the Supreme Court. A writ is a formal judicial order used to protect rights and control unlawful or excessive exercise of public power. Under Article 32, the Supreme Court issues writs for the enforcement of Fundamental Rights. Under Article 226, a High Court can issue writs not only for Fundamental Rights but also, in appropriate cases, for other legal rights. The power therefore belongs to constitutional courts, not to administrative offices or private organisations. A post office, market committee, and sports club may perform useful functions, but none has judicial authority to issue constitutional writs. Thus option B is correct, with the important distinction that High Courts have a wider writ jurisdiction under Article 226.
