Solution

The correct option is D
Assertion is not correct but Reason is correct

Assertion: Substances with hydrogen bonding tend to have unusually high boiling point, because hydrogen bond is strong bond , and to boil the liquid the intermolecular interaction is required to break , and here the Hydrogen bond is the intermolecular interaction.
Reason: Extra energy is required to break the hydrogen bond because this is stronger bond.
Hence, assertion is not correct but reason is correct.
