• A. 4600 ml
• B. 3200 ml
• C. 500 ml
• D. 1200 ml

Answer 1

The correct option is A 4600 ml

Vital Capacity (VC) is defined as a change in volume of lung after maximal inspiration followed by maximal expiration. It is the sum of tidal volume, inspiratory reserve volume and expiratory reserve volume. It is about 80 percent of total capacity, or 4.8 liters, because some air remains in the lungs after exhalation.

So, the correct answer is- 4600ml.
