The correct response highlighting a key difference between using a credit card and getting a loan is:
With a credit card, you should pay the full amount back all at once, while a loan repayment is created for you to pay back smaller amounts over time.
This option correctly distinguishes the typical repayment structures between credit cards and loans. When using a credit card, you can carry a balance from month to month, but you are encouraged to pay it back in full to avoid interest. In contrast, loans usually involve fixed repayments over time.
