Answer :

In the Credits column of a bank statement for a checking account, you would typically find items that increase the balance of your account. Let's go through the options provided:

1. An online bill payment: When you make an online bill payment from your checking account, this would typically appear in the Debits column of your bank statement, not in the Credits column. Online bill payments usually decrease your account balance.

2. Bank fees: Bank fees are charges imposed by the bank for various services or transactions. These would appear in the Debits column of your bank statement as they reduce your account balance, so they would not be found in the Credits column.

3. An ATM withdrawal: Similar to online bill payments, ATM withdrawals reduce your account balance, so they would appear in the Debits column of your bank statement, not in the Credits column.

4. Interest earned: When you earn interest on your checking account balance, this amount is typically added to your account balance, increasing it. Therefore, interest earned would be an example of an item that would appear in the Credits column of a bank statement for a checking account.

In summary, among the options provided, "Interest earned" is the item that would appear in the Credits column of a bank statement for a checking account.
