Solution

The correct option is D III and V
In this question, they want you to find the formula for calculating the total lung capacity. Total lung capacity is the total volume of air accommodated in the lungs at the end of a forced inspiration. This includes Residual Volume (RV) and Vital Capacity (VC) (1200 + 4800 ml).
