• B. The use of tariffs to affect trade.
• C. The creation of public works programs.
• D. The central bank's use of money supply or the interest rate to stabilize the economy.

Answer: (D)

Monetary policy is the central bank’s management of the money supply and interest rates to stabilize the economy. By tweaking how much money is circulating and how costly it is to borrow, the central bank influences spending, investment, inflation, and overall economic activity. When the economy slows and unemployment rises, it can loosen monetary policy—injecting liquidity and lowering interest rates—to encourage borrowing and spending. When inflation is rising, it can tighten policy—reducing money supply or raising rates—to cool demand. This focus on money and credit distinguishes monetary policy from other tools like tax changes or public spending (fiscal policy) or actions that affect trade (tariffs) and public works programs. Tools such as open-market operations, reserve requirements, and the policy rate are all aimed at guiding the economy toward stability.
