Full Explanation
The correct answer is: Overfitting: the model memorized training patterns that do not generalize. This matches standard ML/AI engineering practice for Domain 1: ML Fundamentals. Distractors confuse adjacent concepts or unsafe operational shortcuts. In production, validate with held-out data, monitoring, and governance appropriate to risk.
