When a model performs well on training data but fails to generalize to unseen data.

• A. Bias
• B. Fairness
• C. Overfitting ✓
• D. Underfitting
• E. Interpretability

Correct Answer: C. Overfitting

Explanation

Overfitting occurs when a model learns the training data too intricately—including noise and irrelevant details—making it unable to generalize effectively to new, unseen data. When a model achieves strong performance on training data but performs poorly on unseen data, it exhibits overfitting.
