Solution

The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
$P h_{2} {B r}^{⊖}$ on reaction with $N a O H$ gives benzene diazohydroxide.
Hydroxide ion $O H^{-}$ is a strong nucleophile, attacks the terminal N atom, and forms a covalent bond.
Hence, both Assertion and Reason are correct and Reason is the correct explanation for Assertion
