Match List I with List II :

List I		List II
A	Expiratory capacity	I	Expiratory reserve volume + Tidal volume + Inspiratory reserve volume
B	Functional residual capacity	II	Tidal volume + Expiratory reserve volume
C	Vital capacity	III	Tidal volume + Inspiratory reserve volume
D	Inspiratory capacity	IV	Expiratory reserve volume + Residual volume

Choose the correct answer from the options given below :

The correct answer is A-II, B-IV, C-I, D-III.

To determine the correct matching, let us define each of the pulmonary capacities based on respiratory volumes:

A. Expiratory Capacity (EC) matches with II (Tidal volume + Expiratory reserve volume):
Expiratory capacity is the total volume of air a person can expire after a normal inspiration. It is the sum of Tidal Volume (TV) and Expiratory Reserve Volume (ERV).
$\mathrm{EC}=\mathrm{TV}+\mathrm{ERV}$

B. Functional Residual Capacity (FRC) matches with IV (Expiratory reserve volume + Residual volume):
Functional residual capacity is the volume of air that remains in the lungs after a normal expiration. It is the sum of Expiratory Reserve Volume (ERV) and Residual Volume (RV).
$\mathrm{FRC}=\mathrm{ERV}+\mathrm{RV}$

C. Vital Capacity (VC) matches with I (Expiratory reserve volume + Tidal volume + Inspiratory reserve volume):
Vital capacity is the maximum volume of air a person can breathe out after a forced inspiration. It is the sum of Expiratory Reserve Volume (ERV), Tidal Volume (TV), and Inspiratory Reserve Volume (IRV).
$\mathrm{VC}=\mathrm{ERV}+\mathrm{TV}+\mathrm{IRV}$

D. Inspiratory Capacity (IC) matches with III (Tidal volume + Inspiratory reserve volume):
Inspiratory capacity is the total volume of air a person can inspire after a normal expiration. It is the sum of Tidal Volume (TV) and Inspiratory Reserve Volume (IRV).
$\mathrm{IC}=\mathrm{TV}+\mathrm{IRV}$

Matching these definitions, we find:
A - II
B - IV
C - I
D - III
