Correct answer
B. Tidal volume
Step-by-step solution
Tidal volume is the volume of air inspired or expired during a normal respiration. It is approximately mL for a healthy adult.
Vital capacity is the maximum volume of air a person can breathe in after a forced expiration.
Inspiratory reserve volume is the additional volume of air a person can inspire by a forcible inspiration.
Total lung capacity is the total volume of air accommodated in the lungs at the end of a forced inspiration.
