Solution

The correct option is D A only
Expiatory Reserve Volume (ERV) is the volume of air that can be exhaled forcibly after exhalation of normal tidal volume. Residual volume (RV) is the volume of air remaining in the lungs after maximal exhalation. So, the total volume of air accommodated in the lungs at the end of maximum forceful inspiration includes ERV + RV.
