Given below are two statements :
Statement I : The boiling point of hydrides of Group 16 elements follow the order
\(\text{H}_2 \text{O}>\text{H}_2 \text{Te}>\text{H}_2 \text{Se}>\text{H}_2 \text{S} .\)
Statement II : On the basis of molecular mass, H2O is expected to have lower boiling point than the other members of the group but due to the presence of extensive H-bonding in H2O, it has higher boiling point.
In the light of the above statements, choose the correct answer from the options given below:
1. Both statement I and statement II are false.
2. Statement I is true and Statement II is false
3. Statement I is false but Statement II is true.
4. Both Statement I and Statement II are true.
