What is the first action you should take if you suspect there has been a fraudulent charge on your credit card? aorder your credit report to look for other fraudulent activity. bcall the store where the purchase was made and ask them to remove the charge. cclose all bank accounts associated with that credit card. dcontact the credit card company to report the fraudulent charge.

The best answer is D)Contact the credit card company to report the fraudulent charge

Calling the credit card company will enable you to report the activity and render the card invalid. The company will also inform you of any further action you should take to protect yourself.
Closing all bank accounts associated with the credit card is a "throwing the baby out with the bath water" approach. It likely is not necessary. Ordering your credit report will take too long, and won't tell you anything that the credit card company can't tell you.
