Explanation

In the landmark nine-judge Constitution Bench ruling in Justice K.S. Puttaswamy (Retd.) vs. Union of India (2017), the Supreme Court unanimously declared that the Right to Privacy is a fundamental right.

– The Court established that privacy is an intrinsic, inseparable element of personal liberty, human dignity, and bodily autonomy.
– It emanates directly from the guarantees of life and personal liberty enshrined under Article 21 of the Constitution of India, bolstered by the freedoms protected across Part III.

Therefore, the Right to Privacy is protected under Article 21 — Option C.
