Which amongst the following is not the source of the income of RBI?

The Reserve Bank of India (RBI) earns its income primarily from two sources: domestic income (mainly interest on central and state government bonds held for conducting open market operations and liquidity management, ) and foreign income (earnings from the deployment of foreign currency assets in foreign sovereign bonds and central bank deposits, ). The RBI does not invest in private equity shares of commercial companies, so 'Dividend on the shares of private equity held with the bank' is not a source of RBI income.
