Which of the following will increase the money supply?

increasing the required reserve ratio

an open market sale

raising the discount rate relative to the federal funds rate

none of the above

Answer 1

None of the above

Increasing the required reserve ratio or raising the discount rate will both decrease the money supply. An open market sale won't change the money supply (unless you mean selling bonds, which will decrease the money supply).
