Answer 1

The correct option is B a(iii)., b( i)., c( iv) ., d( ii)

Tidal volume is the lung volume representing the normal volume of air displaced between normal inhalation and exhalation when extra effort is not applied. In a healthy, young human adult, tidal volume is approximately 500 - 550 mL per inspiration.
Inspiratory reserve volume: the maximal amount of additional air that can be drawn into the lungs by determined effort. The IRV is between 2500-3000 mL: in human beings.
Expiratory reserve volume: the additional amount of air that can be expired from the lungs by determined effort after normal expiration.The average ERV volume is about 1000 - 1100 mL.
Residual volume is the amount of air that remains in a person's lungs after fully exhaling. Residual volume (RV), about 1,100 -1,200 mL.
