Solution

The correct option is B Both Assertion and Reason are correct but the Reason is not the correct explanation of the Assertion
As conjugate base of $H N O_{3}$ is more stable due to more no. of resonating structure, so it is more basic. Hence $H N O_{3}$ is a strong acid.

Hence, the correct option is $B$
