D. inspiratory capacity

Answer

c

Explanation

The maximum volume of air that a person can breathe in after forced expiration or the maximum volume of air that a persqn can breathe out after forced inspiration is called vital capacity .
`underset"(Inspiratory reserve volume)"(VC=IRV)underset"(Expiratory reserve volume)"(+ERV)underset"(Tidal volume)"(+TV)`
The value of vital capacity varies from 3400 mL to 4800 mL.
On the other hand. tidal volume is the air inspired or eXpired during normal breathing. Total lung capacity is the volume of air present in lungs and respiratory passage after maximum inspiration. Whereas, inspiratory capacity is total volume of air that a person can inspire after normal inspiration.
