When it sells government securities, it takes money out of the economy.
• Option B: Issuance of different types of bonds. This is not the correct answer. Issuance of different types of bonds is a function of the government, not the central bank. The government issues bonds to raise money. The central bank may buy or sell government bonds, but it does not issue them.
• Option C: Auction of gold. This is not the correct answer. The central bank may auction gold, but this is not a tool that is used to control the money supply or interest rates. The central bank may auction gold to raise money or to regulate the gold market.
• Option D: To make available direct finance to borrowers. This is not the correct answer. The central bank does not make direct loans to borrowers. The central bank may provide liquidity to banks, but it does not make direct loans to businesses or individuals.
