Explanation
A. Residual volume and vital capacity: Total Lung Capacity (TLC) is the sum of every bit of air the lungs can hold. Vital capacity is the maximum air you can move, and residual volume is what remains after you exhale as hard as possible.
B. Tidal volume, inspiratory reserve volume, and expiratory reserve volume: This sum equals the vital capacity, but it misses the residual volume.
C. Residual volume and tidal volume: This is only a small portion of the total capacity.
D. Vital capacity and tidal volume: This is redundant, as tidal volume is already included within the calculation of vital capacity.
