The correct option is D

A – Q; B – T; C – P; D – R; E – S.

Tidal Volume (TV): Volume of air inspired orexpired during a normal respiration. It is approx. 500 mL.

Inspiratory Reserve Volume (IRV):Additional volume of air, a person can inspire by a forcible inspiration. This averages 2500mL to 3000 mL.

Expiratory Reserve Volume (ERV):Additional volume of air, a person can expire by a forcible expiration. This averages 1000mL to 1100 mL.

Residual Volume (RV): Volume of air remaining in the lungs even after a forcible expiration. This averages 1100 mL to 1200 mL.

Inspiratory Capacity (IC): Total volume of air a person can inspire after a normal expiration. This includes tidal volume and inspiratory reserve volume ( TV+IRV).

Expiratory Capacity (EC): Total volume of air a person can expire after a normal inspiration. This includes tidal volume and expiratory reserve volume (TV+ERV).

Functional Residual Capacity (FRC): Volume of air that will remain in the lungs after a normal expiration. This includes ERV+RV.

Vital Capacity (VC): The maximum volume of air a person can breathe in after a forced expiration. This includes ERV, TV and IRV or the maximum volume of air a person can breathe out after a forced inspiration.

Total Lung Capacity: Total volume of air accommodated in the lungs at the end of a forced inspiration. This includes RV, ERV, TV and IRV or vital capacity + residual volume.
