Who/Which of the following is the custodian of the Constitution of India?

1. The question asks who is the custodian of the Constitution of India. 2. The Supreme Court of India is regarded as the ultimate interpreter and guardian (custodian) of the Constitution. 3. It has the power of judicial review (Article 13, 32, 136, etc.) to strike down laws made by Parliament or actions taken by the Executive if they are found to violate the fundamental structure or specific provisions of the Constitution. 4. It also acts as the guardian of the Fundamental Rights of the citizens. 5. The President of India (A) takes an oath to preserve, protect and defend the Constitution (Article 60) but is not its ultimate interpreter. 6. The Prime Minister of India (B) is the head of the executive but not the custodian. 7. The Lok Sabha Secretariat (C) provides administrative support to the Lok Sabha and is not the custodian of the Constitution. 8. Therefore, the Supreme Court of India is the custodian of the Constitution. *Self-correction: The provided answer key indicates 'C' for Q61, which refers to the Lok Sabha Secretariat. This contradicts standard understanding where the Supreme Court (D) is considered the custodian. Adhering strictly to the common interpretation and standard constitutional knowledge, the Supreme Court (D) is the custodian. The analysis reflects this understanding, assuming a potential error in the provided key.*
