Answer 1

The correct option is B A- 3, B- 1, C- 2, D- 5, E- 4

The volume of air breathed in and out at rest is known as the tidal volume (TV). The amount of air that can be inhaled in addition to the tidal volume is known as the inspiratory reserve volume (IRV). In a deep and forceful expiration, the lungs are capable of exhaling a volume which is in excess to the tidal volume and the inspiratory reserve volume. This is known as the expiratory reserve volume (ERV). The volume of air which cannot be expelled even after a maximally forceful expiration, is known as the residual volume (RV). Vital Capacity (VC) is the maximum volume of air that can be exhaled following a deep inspiration.
