Amine group is ortho and para- directing, hence it directs the SO3 electrophile to ortho- and para- positions.

Q. Assertion : Anilinium hydrogensulphate, on heating forms a mixture of ortho- and para-aminobenzene sulphonic acids.
Reason : $p$ -Aminobenzene sulphonic acid exists as zwitter ion.

If both assertion and reason are true and reason is the correct explanation of assertion

If both assertion and reason are true but reason is not the correct explanation of assertion

If assertion is true but reason is false

If both assertion and reason are false

Amine group is ortho and para- directing, hence it directs the $S O_{3}$ electrophile to ortho- and para- positions.
