Correct Answer: Regulating the stock market

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

Regulating the stock market is not a function of the Reserve Bank of India (RBI). The RBI's primary functions include issuing currency notes, regulating the banking system, and conducting monetary policy. It is responsible for maintaining price stability, controlling inflation, and managing the overall monetary and financial stability of the country. The regulation of the stock market falls under the jurisdiction of the Securities and Exchange Board of India (SEBI), which is an independent regulatory body specifically established for this purpose. Therefore, option d. Regulating the stock market is not a function of the RBI.
