The correct answer is option 3, Article 21. The Right to Privacy is protected under Article 21 of the Indian Constitution. Article 21 states that "No person shall be deprived of his life or personal liberty except according to procedure established by law." This means that individuals have the right to privacy and that their personal lives cannot be infringed upon without following the due process of law. The Right to Privacy includes the protection of personal information, freedom from surveillance, and the ability to make personal choices without interference. It is important to note that while other articles of the Constitution may also touch upon aspects of privacy, Article 21 is specifically recognized as a fundamental right with respect to privacy.
