Final answer:
The Federal Reserve System does not include maintaining the balance of trade as one of its primary goals. It focuses on stable prices, full employment, and moderate long-term interest rates. The correct option is (C).
Step-by-step explanation:
The goal of the Federal Reserve System that is NOT listed among its primary objectives is C. to maintain the balance of trade. While the Federal Reserve focuses on fostering a stable economy by managing monetary policy, its main goals include ensuring stable prices, achieving full employment, and maintaining moderate long-term interest rates.
The responsibility for the balance of trade primarily lies with fiscal policy and trade agreements, not with the central bank's monetary policy tools. The Fed does influence the economy by managing the money supply and interest rates, which can indirectly affect the trade balance, but maintaining a trade balance is not one of its direct goals.
