What is one of the rights a bank has regarding customer balances?

A bank typically has the right to demand repayment of overdrawn balances, which is why the chosen answer is appropriate. When a customer overdraws their account, it means they have spent more money than they have available, creating a negative balance. The bank allows this to facilitate transactions, but it also expects to recover those funds. As a result, the bank can call for the repayment of any overdrawn amounts at any time, safeguarding its financial interests and ensuring the account does not remain in deficit indefinitely.

Other options might suggest certain practices banks can adopt, such as charging for withdrawals or requiring minimum balances, but they do not embody the fundamental and immediate right of banks to call back funds that are owed due to an overdraft. Therefore, the correct choice reflects a critical aspect of banking operations concerning account management and customer responsibilities.
