Solution

The correct option is D
Greater than tidal volume

Residual volume is always greater than tidal volume. Tidal volume is the volume of air normally inspired or expired in one breath without any effort, and the residual volume of air is the air which remains in the lungs even after forcible expiration. Tidal volume is about 500 ml, whereas residual volume is about 1100-1200 ml.
