The correct answer is (c). Equitable distribution of income and assets is not an objective of monetary policy.
Monetary policy is the use of money supply and interest rates to influence the economy. The goals of monetary policy are to promote economic growth, low unemployment, and stable prices.
Equitable distribution of income and assets is a goal of fiscal policy, not monetary policy. Fiscal policy is the use of government spending and taxation to influence the economy.
The other options are all objectives of monetary policy. Price stability is the goal of keeping inflation low and stable. Economic stability is the goal of avoiding recessions and booms. Foreign exchange rate stability is the goal of keeping the value of the currency relatively stable against other currencies.
