Correct answer: A

Tidal volume(TV) is the volume of air inspired or expired during a normal respiration. It is approx. 500 mL.

Inspiratory reserve volume(IRV) average 2500-3000 mL and is the additional volume of air inspired forcibly by a person.

Expiratory reserve volume (ERV) is additional volume of air a person can be expired by a forceful expiration. This averages 1000 - 1100 mL.

Residual volume (RV) is volume of air remaining in lungs even after forceful expiration. This averages 1100 - 1200 mL.
