Answer:
d. Your bank's balance sheet shows a decrease in reserves by $100 and a decrease in deposits by $100.
Explanation:
A checking account represents a bank account which provides greater liquidity and convenience with respect to withdrawals and deposits. Such accounts are usually maintained by financial institutions.
A checking account allows the account holder to withdraw and deposit as many times as per the need unlike a savings account whereby some restriction is placed.
In the given case, withdrawal of cash from bank would reduce the balance of deposits. Deposits represent a liability to the bank as it's an obligation to be met.
Banks are required to maintain reserves as a proportion of their deposits. So when deposits get reduced, so will the reserves.
