The correct answer is (c), BSE.
The BSE Municipal Bond Index (BSE MBI) is a market-capitalization-weighted index of municipal bonds listed on the BSE. The index was launched in 2009 and is designed to provide a benchmark for the performance of the Indian municipal bond market. The BSE MBI is a transparent and liquid index that is widely used by investors to track the performance of the Indian municipal bond market.
The RBI is the central bank of India and is responsible for regulating the country’s financial system. SEBI is the Securities and Exchange Board of India and is responsible for regulating the country’s securities market. NSE is the National Stock Exchange of India and is the largest stock exchange in India.
The RBI, SEBI, and NSE are all important institutions in the Indian financial system. However, none of these institutions launched India’s first Municipal Bond Index. The BSE MBI was launched by the BSE, which is a stock exchange.
