Select the most likely consequence of making payments late to a card that has an introductory rate

The question has multiple choices

A. Fees and paying the default interest rate on the balance
B. Fees and paying the introductory interest rate on the balance
C. Paying higher interest rates
D.  None of these answers are correct

The answer is A) Fees and paying the default interest rate on the balance

Always, there is a non-fee period defined by the bank. Creditors will not only penalize you with a late fee, but also will most of the times increase your interest rate to the penalty rate. When your payment becomes sixty days past due, the introductory rate can expire prematurely.
