Identify the correct and incorrect match about respiratory volume and capacities and mark the correct answer

(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)
