When $1200\text{ }\!\!~\!\!\text{ mL}$ air is left in the lungs, it is called
1 vital capacity
2 tidal volume
3 residual volume
4 inspiratory reserve volume
Explanation:
(c) Residual volume (RV) is the volume of air remaining in lungs even after a forcible expiration. It is about 1100 $1200\text{ml}$.

Vital capacity of our lungs is
1 total lungcapacity minus residual volume.
2 inspiratory reserve volume plus tidal volume.
3 total lung capacity minus expiratory reserve volume.
4 inspiratory reserve volume plus expiratory reserve volume.
Explanation:
(a) Vital capacity (VC) is the volume of air that can breathe in after a forced expiration or volume of air that can breathe out after a forced inspiration (ERV + TV + IRV).
