If a person writes a check for more money than he has in his checking account, what does he need for the check to be paid by the bank?

When a person writes a check for more money than they have in their checking account, overdraft protection is the necessary feature that allows the check to be paid by the bank. Overdraft protection acts as a safety net, enabling the bank to cover the transaction even when the account balance is insufficient. This means that the bank will either cover the excess amount temporarily or link to another account (such as a savings account) or a line of credit to fulfill the payment of the check.

Without overdraft protection, the check would likely bounce, resulting in fees for the account holder and potential implications for their financial reputation. Other options, such as loan approval or extended account privileges, do not effectively address the immediate need to cover the check amount, while cash reserves refer to available cash rather than an overdraft solution. Thus, overdraft protection is the appropriate and correct choice in this scenario.
