The correct response is:
A decrease in the money supply decreases the ability for assets and securities to be turned to cash. The liquidity in the markets decreases as a result and the bank has less ability to lend.
When the money supply decreases, banks have less liquidity, making it more difficult for them to obtain cash for lending purposes. This reduction in liquidity can lead to tighter lending conditions, as banks may be more cautious and less willing to extend credit when they have fewer cash reserves.
