Solution

The correct option is C Assertion is correct but Reason is incorrect

The intramolecular hydrogen bond is the bond of hydrogen with an atom with another atom of the same molecule.
o -nitrophenol forms intra hydrogen bond while para and meta form intermolecular hydrogen bond.

So, ortho nitrophenol is more volatile than para and meta nitrophenol.
