In the following question two Statement-I (Assertion) and Statement-2 (Reason) are provided. each question has 4 choices (a), (b), (c) and (d) for its answer, out of which Only One is correct. Mark your responses from the following options:
Statement-1: Aniline becomes more reactive towards electrophilic aromatic substitution in presence of strongly acidic solution.
Statement-2: The amino group is completely protonated in strongly acidic medium. Thus the lone pair of electrons on the nitrogen is no longer available for resonance.

Both Statement-1 and Statement-2 are true and Statement-2 is the correct explanation of Statement-1.
Both Statement-1 and Statement-2 are true and Statement-2 is not the correct explanation of Statement-1.
Statement-1 is true but Statement-2 is false.
