What is the first action you should take if you suspect there has been a fraudulent charge on your credit card?

I believe the answer is: D Contact the credit card company to report the fraudulent charge

After you make the report, the Credit Card company would block your credit card. This prevent the perpetrator to further conduct his/her activities using your credit card. They would also conduct an investigation on the transactions made with your credit card to pinpoint the perpetrator's location.
