The largest volume of air that may be exhaled following a powerful inhale is referred to as vital capacity. The sum of tidal volume (TV), inhalatory reserve volume (IRV), and expiratory reserve volume (ERV), or total lung capacity less residual volume, is what is meant by this term. It ranges from 4.1 to 4.6 litres.
The correct option is (C): IRV + ERV + TV
