Solution

The correct option is C Assertion is correct but Reason is incorrect
In $p - n i t r o p h e n o l$ intermolecular hydrogen bonding is present while in $o - n i t r o p h e n o l$ intramolecular hydrogen bonding present.
$I n t e r m o l e c u l a r h y d r o g e n b o n d ≫ I n t r a m o l e c u l a r h y d r o g e n b o n d$
So the correct answer is [C].
