Answer:
d) The Fed lowers the discount rate from 4 percent to 2 percent.
Step-by-step explanation:
The federal discount rate is the interest rate charged by central bank to other banks.
The federal discount rate is used as an instrument to control the economy.
A decrease in the discount rate makes it cheaper for commercial banks to borrow money resulting into increased lending activity throughout the economy which is usually part of expansionary monetary policy.
Conversely, a hike in discount rate makes it more expensive for banks to borrow money leading to slowdown of economy which is part of contractionary monetary policy.
