Solution

The correct option is C Statement I is true but statement II is false
It has intramolecular hydrogen bonding and steam volatile.

Melting point is not effected by intramolecular hydrogen bonding but boiling point of a molecule decreases on intramolecular hydrogen bonding.

Hence, statement I is true, but statement II is false.
