Observe the given spirogram where specific respiratory capacities and volumes are indicated by brackets labeled A, B, C, and D. Match the labels in List I with their corresponding terms in List II. List I List II A Label A I Functional residual capacity B Label B II Vital capacity C Label C III Residual volume D Label D IV Inspiratory capacity Choose the correct answer from the options given below :

Step-by-step solution

Label A represents the total volume of air a person can inspire after a normal expiration. This is the sum of tidal volume and inspiratory reserve volume, which is known as inspiratory capacity. Thus, A matches with IV. Label B represents the volume of air that remains in the lungs after a normal expiration. This is the sum of expiratory reserve volume and residual volume, which is known as functional residual capacity. Thus, B matches with I. Label C represents the maximum volume of air a person can breathe out af
