Solution

The correct option is A IRV $+$ ERV $+$ TV
Vital capacity (VC) is the maximum amount of air a person can expel from the lungs after a maximum inhalation. It is equal to the sum of inspiratory reserve volume (IRV), tidal volume (TV), and expiratory reserve volume (ERV).
So, the correct option is A.
