Question

Accepted Answer

## Model Answer **(b) F1 Score** ## Explanation F1 Score is defined as the harmonic mean of precision and recall, combining both into a single metric. The source explicitly states: "F1-Score provides a way to combine both precision and recall into a single measure that captures both properties." Accuracy measures correct predictions overall; reliability and punctuality are not ML evaluation metrics.
