The correct response is:
Fractional-reserve banks issue depositor funds to borrowers, increasing the number of claims made on the same dollars.
In a fractional-reserve banking system, banks keep a fraction of deposits as reserves and lend out the rest. This practice effectively increases the money supply because it allows banks to create new loans, which increases the total amount of money in circulation through a process known as the money multiplier. Each loan made can lead to further deposits and subsequent loans, resulting in multiple claims on the same initial deposit.
