Answer: (D)

$A-Q;B-T;C-P;D-R;E-S$

Residual volume (RV) is the volume of air still remaining in the lungs after the most forcible expiration possible. This accounts for 1100-1200 ml.

The inspiratory reserve volume (IRV) is the additional amount of air that can be inhaled after a normal inhalation. This is the amount of air which can be taken in by forced inhalation. This accounts for 2500-3000 ml.

Vital capacity (VC) is the maximum amount of air a person can expel from the lungs after a maximum inhalation. This accounts for 4000-4600 ml.

The expiratory reserve volume (ERV) is the additional amount of air that can be exhaled after a normal exhalation. This accounts for 1000-1100 ml.

Inspiratory Capacity (IC) is the maximum amount of air that can be inspired. The amount of air for IC is about 3000-3500 ml.

Thus, the correct answer is option D.
