Vital capacity is the maximum amount of air a person can exhale after a deep breath in. It is equal to the sum of the inspiratory reserve volume (the amount of air that can be inhaled beyond a normal breath), tidal volume (the amount of air normally inhaled and exhaled), and expiratory reserve volume (the amount of air that can be exhaled beyond normal exhalation). Therefore, the best choice is B as it includes all three of these volumes.
