Answer:
C. loaning money that would otherwise be held in a bank.
Explanation:
Fractional reserve banking increases the money supply in an economy by "loaning money that would otherwise be held in a bank."
Fractional reserve banking is known as a system of banking whereby the banks hold a fraction of what customers deposit as reserves. Then the banks use the remaining to give loans and thereby creating and increasing the supply of money. Commercial banks practise this type of banking system. This tells of how commercial banks are affecting the money supply. The bank reserves are usually held as cash in the bank. It can also as balances in the bank's account at their central bank.
