Which article empowers the Supreme Court to issue writs for enforcement of fundamental rights?

Article 32 of the Indian Constitution specifically empowers the Supreme Court to issue writs for the enforcement of fundamental rights. This provision is a crucial part of the constitutional framework as it not only enables individuals to approach the Supreme Court directly if they feel their fundamental rights have been violated, but also establishes the Supreme Court as the guardian of these rights.

The articles mentioned in the other choices have different roles within the Constitution. For instance, Article 21 guarantees the right to life and personal liberty, while Article 14 provides the right to equality before the law and equal protection of the laws. Article 226, on the other hand, empowers the High Courts to issue writs, but this is separate from the specific authority of the Supreme Court outlined in Article 32. Thus, the uniqueness of Article 32 in relation to the Supreme Court's role in protecting fundamental rights makes it the correct choice.
