1. Inspiratory capacity $\text{(IC)} =$ Tidal Volume $+$ Residual Volume.
2. Vital Capacity $\text{(VC)} =$ Tidal Volume $\text{(TV)} +$ Inspiratory Reserve Volume $\text{(IRV) +}$ Expiratory Reserve Volume $\text{(ERV).}$
3. Residual Volume $\text{(RV)} =$ Vital Capacity $\text{(VC)} –$ Inspiratory Reserve Volume $\text{(IRV).}$
4. Tidal Volume $\text{(TV)} =$ Inspiratory Capacity $\text{(IC)} –$ Inspiratory Reserve Volume $\text{(IRV).}$

$I$.$PTH$    $II$. $T_{4}$ and $T_{3}$   $III$. $TCT$

The correct option is
