Mark the correct option:
(i) Inspiratory capacity (IC) = Tidal volume + Residual volume
(ii) Vital capacity (VC) = Tidal volume (TV) + Inspiratory reserve volume (IRV) + Expiratory reserve volume (ERV)
(iii) Residual volume (RV) = Vital capacity (VC) + Inspiratory reserve volume (IRV)
(iv) Tidal volume (TV) = Inspiratory capacity (IC) – Inspiratory reserve volume (IRV)
