• A. Meaningful Questions
• B. Monetary Policy
• C. Monopoly
• D. Migration

Answer: (B)

Monetary policy is the policy that uses central bank actions to influence how much money is circulating and what interest rates cost. The central bank uses tools like open market operations (buying or selling government bonds), reserve requirements for banks, and the discount rate to shape lending and borrowing. When the goal is to stimulate the economy, it can increase the money supply and lower interest rates, making loans cheaper and encouraging spending and investment. When inflation or overheating is a concern, it can tighten the money supply or raise rates, making borrowing more expensive and slowing demand. This is different from choices like Monopoly (a market structure) and Migration (population movement), which aren’t about managing money supply and interest rates. So the policy described is monetary policy.
