Answer:
The correct answer is option c.
Step-by-step explanation:
If the Federal bank sells securities to a bond dealer, the dealer will need to pay back the Fed. This will cause a reduction in the dealer's bank's transaction deposits liabilities.
A reduction in deposits liabilities will further cause a reduction in the total reserves of the bank. Consequently, it will cause a decrease in the money supply. In this way, the federal reserve bank can curb inflationary pressures.
