Assertion: Anilinium chloride is more acidic than ammonium chloride. Reason: Anilinium ion is resonance stabilized.

Both Assertion and Reason are correct and the Reason is the correct explanation for the Assertion. Both Assertion and Reason are correct and the Reason is not the correct explanation for the Assertion. Assertion is correct but the Reason is incorrect. Both Assertion and Reason are incorrect.

Assertion is correct but the Reason is incorrect.

Correct Reason: Since ammonia is a stronger base than aniline, therefore, the conjugate acid of aniline, i.e., anilinium chloride is more acidic than conjugate acid of ammonia, i.e., ammonium chloride.
