Solution

The correct option is B Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion.
Friedel–Crafts alkylation involves the alkylation of an aromatic ring with an alkyl halide using a strong Lewis acid catalyst with anhydrous ferric chloride as a catalyst, the alkyl group attaches at the former site of the chloride ion.

$R - C l + A l C l_{3} ⟶ R^{+} + A l {C l}_{4}^{-}$

$A l {C l}_{3}$ forms a salt with aniline $(C_{6} H_{6} {N H}_{2}^{+} A l {C l}_{3}^{-})$ which deactivates the benzene ring thereby preventing Friedel-Crafts reaction.
