To solve this problem, we need to match the respiratory volumes and capacities in List I with their corresponding formulas in List II. Let's analyze each item:$\newline \bullet$A. Expiratory capacity:$\newline$ - Expiratory capacity is the total volume of air that can be expired after a normal inspiration.$\newline$ - It is calculated as the sum of Tidal Volume (TV) and Expiratory Reserve Volume (ERV).$\newline$ - This matches with II.$\newline \bullet$B. Functional residual capacity:$\newline$ - Functional residual capacity is the volume of air remaining in the lungs after a normal expiration.$\newline$ - It is calculated as the sum of Expiratory Reserve Volume (ERV) and Residual Volume (RV).$\newline$ - This matches with IV.$\newline \bullet$C. Vital capacity:$\newline$ - Vital capacity is the maximum amount of air a person can expel from the lungs after a maximum inhalation.$\newline$ - It is calculated as the sum of Tidal Volume (TV), Inspiratory Reserve Volume (IRV), and Expiratory Reserve Volume (ERV).$\newline$ - This does not directly match any given option, but it is often associated with the sum of inspiratory and expiratory volumes.$\newline \bullet$D. Inspiratory capacity:$\newline$ - Inspiratory capacity is the maximum amount of air that can be inspired after a normal expiration.$\newline$ - It is calculated as the sum of Tidal Volume (TV) and Inspiratory Reserve Volume (IRV).$\newline$ - This matches with III.$\newline$Now, let's match the items from List I with List II:$\newline A \rightarrow II, B \rightarrow IV, C \rightarrow I, D \rightarrow III \newline$This corresponds to Option 3.
