Answer:
A. Direct deposit
Step-by-step explanation:
A credit in a checking account is an amount of money that is deposited into that particular account. Therefore, from the available options, only a direct deposit into a checking account would be considered a credit on the account statement.
The other options are forms of debits or debts owed, and a check written is not active until its cashed and its not deposited into the account because you get cash at the counter.
