A bank deploys an AI system that flags unusual card transactions in real time by comparing each transaction with the customer's normal pattern. Which statement about this use is most accurate?

The system uses anomaly detection to support fraud prevention. It learns each customer's normal spending pattern and flags transactions that deviate sharply in real time, so suspicious activity can be stopped or verified quickly without reviewing every transaction by hand.

  1. AIt relies on anomaly detection to support fraud preventionCorrect
  2. BIt works only if every transaction is manually reviewed first
  3. CIt replaces the need for any customer data
  4. DIt is a tool used only for advertising

Explanation

Fraud detection systems learn a customer's usual behaviour and flag deviations, which is anomaly detection. They need data rather than avoid it, operate automatically at scale rather than after manual review, and serve risk control rather than advertising.
