The correct statement regarding the basicity of arylamines is

What occurs during the Hofmann rearrangement in the conversion of an amide to an amine?

Explain the reaction of amines with arylsulphonyl chlorides.

Given below are two statements:
Statement $I$ : The $NH_2$ group in Aniline is ortho and para directing and a powerful activating group.
Statement $II$ : Aniline does not undergo Friedel-Craft's reaction (alkylation and acylation).
In the light of the above statements,choose the most appropriate answer from the options given below :

Assertion $(A)$: $-NH_2$ group of aniline is ortho,para directing in electrophilic substitutions.
Reason $(R)$: $-NH_2$ group stabilises the arenium ion formed by the ortho,para attack of the electrophile.
The correct answer is
