Correct Answer: Regulating the stock market

Solution : The correct answer is (d)  Regulating the stock market.

Regulating the stock market is not a direct function of the Reserve Bank of India (RBI). The RBI primarily focuses on monetary policy, currency management, and regulation of the banking system.

However, the regulation of the stock market falls under the jurisdiction of the Securities and Exchange Board of India (SEBI), which is the regulatory authority for the securities market in India.
