Solution

The correct option is D
A, C, D are correct

The abbreviations stand for the following:

IRV - Inspiratory Reserve Volume

TV - Tidal Volume

ERV - Expiratory Reserve Volume

RV - Residual Volume

IC - Inspiratory Capacity

FRC - Functional Residual Capacity

VC - Vital Capacity

RV - Residual Volume

TLC - Total Lung Capacity

From the figure, it is clear that

FRC = ERV + RV

So, A, C and D are correct.
