Answer 1

Answer: (B), (C)

The correct options are

Tidal volume is the volume of air inspired or expired during a normal unforced breathing. It is approximately 500 ml, which means, a healthy man can inspire or expire approximately 6000 to 8000 ml of air per minute.
Inspiratory capacity is the total volume of air a person can breathe in after a normal expiration. It is 3500 ml.
