Assertion: In strongly acidic solution, aniline becomes less reactive towards electrophilic reagents. Reason: Due to protonation of amino group the lone pair of electrons on nitrogen is not available for donation to benzene ring by resonance.

In strongly acidic medium, aniline is protonated, so LP es are not available to produce mesomeric or electromeric effect; thus, aniline becomes less reactive towards SE reactions.
