Final answer:
Sam has experienced c. identity theft, where his personal bank card information was used without his consent to make unauthorized purchases at a sports store.
Step-by-step explanation:
Sam is a victim of c. identity theft, which is a risk associated with using financial institutions. Identity theft, sometimes referred to as 'True-name Fraud,' occurs when someone wrongfully acquires and uses a consumer's personal identification, credit, or account information without their permission. The illegally acquired information, such as a social security number, pin number, or password, is then used to steal a person's identity. In Sam's case, thieves have charged hundreds of dollars at a sports store using his bank card information, draining his bank account and possibly making large unauthorized purchases.
