The correct answer is option 4, Supreme Court and High Courts. Writs are legal orders issued by courts to direct a person or an authority to do something or refrain from doing something. In India, writs can be issued by both the Supreme Court and the High Courts. The Supreme Court has the power to issue writs under Article 32 of the Constitution, which is known as the "Right to Constitutional Remedies." The High Courts, on the other hand, have the power to issue writs under Article 226 of the Constitution. These writs can be used to protect fundamental rights and ensure justice. Therefore, both the Supreme Court and High Courts have the authority to issue writs, making option 4 the correct answer.
