Final answer:
The correct answer is b. Reserves increase by $10 million, Bonds decrease by $10 million. When the Fed conducts an open market purchase, it buys Treasury bonds from a bank, which increases the bank's reserves. In this case, Acme Bank's reserves will increase by $10 million due to the open market purchase by the Fed. However, in order to convert the bond sale proceeds to new loans, Acme Bank will have to reduce its bond holdings by $10 million, resulting in a decrease in bonds.
