Solution

The correct option is B Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
Aniline hydrogen sulphate on heating decomposes to aniline and $H_{2} {S O}_{4}$ . Sulphonation of aniline with $H_{2} {S O}_{4}$ takes place ( $S_{E}$ reaction) at $o -$ and $p -$ positions, since $(- {N H}_{2})$ group is $o -$ and $p -$ directing.
