Correct option is C
The correct answer is (c) Reserve Bank of India
A constitutional body is one that is established directly by the Constitution of India, with its structure, powers, and functions defined in the Constitution itself.
The Reserve Bank of India (RBI), though highly important, is not a constitutional body. It was established under the Reserve Bank of India Act, 1934, which makes it a statutory body.
In contrast, the Election Commission of India (Article 324), Comptroller and Auditor-General of India (Article 148), and National Commission for Backward Classes (Article 338B, added by the 102nd Constitutional Amendment Act, 2018) are all constitutional bodies.
Information Booster:
Election Commission of India: Established under Article 324, conducts elections to Parliament, State Legislatures, and the offices of President and Vice-President.
Comptroller and Auditor-General (CAG): Mentioned in Article 148, audits accounts of the Union and State governments.
National Commission for Backward Classes (NCBC): Made a constitutional body by the 102nd Amendment Act, 2018 through Article 338B.
Reserve Bank of India (RBI): A statutory body, not mentioned in the Constitution.
Additional Information:
Statutory bodies are created by Acts of Parliament, e.g., RBI, SEBI, NITI Aayog.
Constitutional bodies derive their authority directly from the Constitution.
Extra-constitutional bodies have no mention in the Constitution or statutory status (e.g., Planning Commission, now replaced by NITI Aayog).
