Answer 1

The correct option is B total lung capacity

The maximum amount of air the lungs can hold after forceful inspiration is called total lung capacity (TLC). Its value is about 5450ml.
Residual volume (RV) is the volume of air that is left in the lungs even after forceful exhalation. It is about 1100ml-1200ml.
Vital capacity (VC) is the maximum volume of air that can be breathed out after a forceful inspiration. Its value is about 4300ml.
Tidal volume (TV) is the volume of air taken in and out of the lungs during normal breathing. The value of the tidal volume is 500 ml.
