Solution

The correct option is B Both Assertion and Reason are correct and Reason is not the correct explanation for Assertion
The heat of vaporization of water is $40.65$ kJ/mol.

The heat of fusion for water is $6.02$ kJ/mol.

Also when water vaporizes or freezes, its chemical composition does not change.
