Credit Card Disadvantages
One disadvantage of credit cards is that they may encourage you to overspend. This can lead to serious financial trouble. Only charge as much as you can repay in full when the bill arrives. What happens if you don't pay off your credit card balance each month?
You won't be required to pay anything extra.
You will be charged interest.
You will need to take out another credit card to pay off what you owe on this one.
"B" is correct. Over time interest can really add up, especially if you only make the minimum monthly payment. Taking out a new credit card to pay the balance on an old one is likely to leave you owing even more.
