Given below are two statements:

Statement $I$: The boiling point of hydrides of Group $16$ elements follow the order

$\mathrm{H}_2 \mathrm{O}>\mathrm{H}_2 \mathrm{Te}>\mathrm{H}_2 \mathrm{Se}>\mathrm{H}_2 \mathrm{~S}$.

Statement $II$: On the basis of molecular mass, $\mathrm{H}_2 \mathrm{O}$ is expected to have lower boiling point than the othe members of the group but due to the presence of extensive $\mathrm{H}$-bonding in $\mathrm{H}_2 \mathrm{O}$, it has higher boiling point.

In the light of the above statements, choose the correct answer from the options given below:

$C{{l}_{2}}\left( g \right)+Ba{{(OH)}_{2}}\to X\left( aq. \right)+BaC{{l}_{2}}+{{H}_{2}}O$

$X + {H_2}S{O_4} \to Y + BaS{O_4}$

$Y\xrightarrow[{\Delta \, > \,365\,K}]{\Delta }Z + {H_2}O + {O_2}$

$Y$ and $Z$ are respectively
