Final answer:
Making only minimum payments is an example of poor credit card management.
Step-by-step explanation:
The correct answer is C) Making only minimum payments.
Making only minimum payments is an example of poor credit card management. When you make minimum payments, you are not paying off the full balance each month, which means you will continue to accrue interest on the remaining balance. This can lead to a cycle of debt and make it harder to pay off the credit card in the long run.
