| 金声玉亮2.0 | C. Buying Treasury securities from commercial banks. Explanation: Expansionary monetary policy is used to stimulate economic growth by increasing the money supply and reducing interest rates. When the Federal Reserve buys Treasury securities from commercial banks, it injects money into the economy, which can lead to increased lending, spending, and economic activity. This is an example of expansionary monetary policy. The other options are incorrect because: A. Increasing the discount rate would make borrowing more expensive and reduce the money supply, which is a contractionary monetary policy. B. Increasing the reserve ratio would require commercial banks to hold more reserves and reduce their lending, which is also a contractionary monetary policy. D. Lowering income taxes is a fiscal policy, not a monetary policy, and is not a direct action taken by the Federal Reserve. |
