1. Correct Answer: Option D: I, II and V
 2. Explanation:
     ● 1 is correct: The Reserve Bank of India (RBI) engages in open market operations, which involve buying and selling government bonds. This activity helps regulate the money supply and serves as a key source of income for the RBI. The RBI earns interest on these bonds and can also benefit from favorable movements in bond prices.  
     ● 2 is correct: Under the Foreign Exchange Management Act, 1999 (FEMA), the RBI manages the country's foreign exchange reserves. Its activities in the foreign exchange market, such as buying U.S. dollars at lower rates and selling them at higher rates, contribute to its profits.  
     ● 3 is incorrect: The RBI does not manage pension funds. Pension fund management in India is overseen by the Pension Fund Regulatory and Development Authority (PFRDA).  
     ● 4 is incorrect: The RBI does not directly lend to private companies. It primarily lends to commercial banks and financial institutions, which then lend to private companies and individuals.  
     ● 5 is correct: The RBI is the sole authority to issue banknotes in India, as designated by the RBI Act, 1934. While the RBI incurs printing costs, it earns seigniorage, which is the profit from the difference between the face value of the currency and its production cost. This seigniorage acts as a source of income for the RBI.
