Final answer:
When a lost or stolen credit card is reported within 48 hours, the credit card will be deactivated to prevent fraudulent charges.
Step-by-step explanation:
If your credit card is lost or stolen and you report it within 48 hours, the correct answer is B. The card will be deactivated. Reporting your lost or stolen card promptly ensures that you are not responsible for any unauthorized charges made after your report. Most card issuers will shut down your card to prevent further fraud. You might want to keep a record of your account numbers, their expiration dates, and the phone number and address of each company in a secure place.
