Vedclass · Answer

(B) The correct answer is $B$. Vital capacity $(VC)$ is the maximum volume of air a person can breathe in after a forced expiration. It is the sum of tidal volume $(TV)$,inspiratory reserve volume $(IRV)$,and expiratory reserve volume $(ERV)$. Total lung capacity $(TLC)$ is the total volume of air accommodated in the lungs at the end of a forced inspiration,which includes $VC$ and residual volume $(RV)$. Therefore,$TLC = VC + RV$,which implies $VC = TLC - RV$.
