The statement clarifies that both the inspiratory reserve volume (IRV) and expiratory reserve volume (ERV) are measured separately from the tidal volume. IRV is measured from the completed resting inspiration, while ERV is measured from the completed resting expiration. Therefore, neither IRV nor ERV includes the tidal volume in their measurement.

Option 4 is the correct answer.
