Statement II : Complex $\left[\mathrm{Co}\left(\mathrm{NH}_3\right)_6\right]^{3+}$ has only one kind of ligands but $\left[\mathrm{Co}\left(\mathrm{NH}_3\right)_4 \mathrm{Cl}_2\right]^{+}$has more than one kind of ligands. In the light of the above statements, choose the correct answer from the options given below.

Given below are two statements: Statement I: The boiling point of hydrides of Group 16 elements follow the order $\mathrm{H}_2 \mathrm{O}\gt\mathrm{H}_2 \mathrm{Te}\gt\mathrm{H}_2 \mathrm{Se}\gt\mathrm{H}_2 \mathrm{~S} \text {. }$ Statement II: On the basis of molecular mass, $\mathrm{H}_2 \mathrm{O}$ is expected to have lower boiling point than the other members of the group but due to the presence of extensive H -bonding in $\mathrm{H}_2 \mathrm{O}$, it has higher boiling point.
