Solution

The correct option is B I- RV, II- TV, III- TLC
Residual volume (RV) is the amount of air that remains in a person's lungs after fully exhaling This averages 1100 mL to 1200 mL.

Tidal volume (TV) of air inspired or expired during normal respiration. It is approximately 500 mL.

Total lung capacity (TLC) is the total volume of air accommodated in the lungs at the end of forced inspiration. This includes RV, ERV, TV and IRV or vital capacity + residual volume. It is around 5000 mL - 6000 mL.
