Answer:
The correct answer is A. If a credit card balance is not paid in full within the grace period then the customer will receive a finance charge.
Step-by-step explanation:
If the credit card account is not paid before the due date, the banks add to the amount to pay a financial charge, which is nothing more than a sum of interest on arrears as a result of the loan.
That is, the financial charge operates as a punitive interest on the grounds of not paying in the indicated period the totality of the credit card account.
