Answer:
B. Ensuring that all of your credit card bills are paid on time
Step-by-step explanation:
A credit card charge interests on outstanding balances and late payments, among other items. Interests in outstanding balances form a big proportion of credit card charges. Therefore, if one can avoid interest on these balances, their credit card charges will reduce greatly.
Paying the entire balance on the credit card statement ensures one does not incur any interest. Ensuring that all of your credit card bills are paid on time is the most appropriate way of managing credit card debts.
