Answer:
The correct answer is letter "C": overdraft fee.
Step-by-step explanation:
A financial institution charges an overdraft fee when the balance of an account does not have enough funds to make a payment but it does go through. Usually, banks give account holders the freedom to choose if having or not this feature in their accounts since, as the fee is charged every time a transaction goes through when the account has a negative balance, it can lead customers to have potential debts.
In that case, an overdraft fee is not a credit in an account. As a charge, it represents a debit.
