Right to Privacy and Article 21: Article 21 of the Indian Constitution guarantees the right to life and personal liberty. In the landmark 2017 judgment of K.S. Puttaswamy (Retd.) vs. Union of India, the Supreme Court of India unanimously held that the right to privacy is an intrinsic part of Article 21. This ruling reinforced privacy as a fundamental right, ensuring protection against unwarranted state and private intrusions.

Part III of the Constitution covers Fundamental Rights, which include:

• Article 19: Right to freedom of speech and expression, freedom of movement, and other essential liberties.
• Article 21: Right to life and personal liberty, which now includes privacy after the Puttaswamy judgment.

Article 14: Ensures equality before the law, but does not explicitly deal with privacy.

Article 17: Abolishes untouchability. Directive Principles of State Policy (DPSPs) are non-enforceable guidelines, not fundamental rights.

Article 24: Prohibits child labor but has no relation to privacy.

Thus, the right to privacy is most closely linked to Article 21 and the freedoms guaranteed in Part III of the Indian Constitution. Hence the correct answer is option (c).
