Model Answer
(B) Accuracy
Accuracy is defined as the percentage of correct predictions out of all the observations.
Explanation
The question directly defines Accuracy — the ratio of correct predictions to total predictions, expressed as a percentage. Precision = TP/(TP+FP); Recall = TP/(TP+FN); F1 combines both. Don't confuse them.
