From the following relationships between respiratory volume and capacities, 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) |
