Solution

The correct option is B $2500 - 3000$ ml
B. 2500-3000 ml
Reason: Respiratory volume is the volume of air which our lung can hold or release under certain different condition. There are four standard lung volumes. Those are Tidal Volume (TV), Inspiratory Reserve Volume (IRV), Expiratory Reserve Volume (ERV) and Residual Volume (RV). Among them, inspiratory reserve volume is the extra amount of air a healthy person can inspire forcefully. This volume can be 2500-3000 ml in average. So the correct option is B.
