• C. A - 1, B - 4, C- 2, D - 3
• D. A - 4, B - 3, C- 2, D - 1

Answer 1

The correct option is A A - 1, B - 2, C- 3, D - 4

Inspiratoty Capacity (IC) is volume of air a person can inspire after a normal expiration. This includes tidal volume and inspiratory reserve volume (TV+IRV).

Expiratoty Capacity (EC) is total volume of air a person can expire after a normal inspiration. This includes tidal volume and expiratory reserve volume (TV+ERV).

Functional Residual Capacity (FRC) is volume of air that will remain inthe lungs after a normal expiration. This includes ERV+RV.

Vital Capacity (VC) is maximum volume of air a person can breathe in after a forced expiration. This is summed up by ERV, TV and IRV

Thus correct option is A.
