Choose the correct answer from the options given below:

Match List I with List II.

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

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 $$\mathrm{H}$$-bonding in $$\mathrm{H}_2 \mathrm{O}$$, it has higher boiling point.
