Answer
- D Under new financial regulations, a previously low-risk transaction type is considered high-risk
Explanation
New financial rules can mean that a type of transaction that used to be harmless is now considered risky. The inputs look the same as always, but the right answer is different. The model's learned boundaries no longer fit, and it is wrong more often. That is concept drift. New phishing tricks, by contrast, change the inputs themselves; that is data drift.
