The correct option is C inspiratory reserve volume
Inspiratory reserve volume (IRV) is the additional volume of air that a person can inspire by a forcible inspiration. The average IRV is 2500 mL to 3000 mL.
Tidal volume is the amount of air that moves in or out of the lungs with each respiratory cycle.
Expiratory Reserve Volume (ERV) is the additional volume of air that a person can expire by a forcible expiration. The average ERV is 1000 mL to 1100 mL.
Residual volume (RV) is the volume of air remaining in the lungs after maximum forceful expiration. In other words, it is the volume of air that cannot be expelled, thus causing the alveoli to remain open at all times. Values for residual volume are 1 to 1.2 L.
