• D. None of the above

Answer 1

The correct option is B

Explanation for correct option:

(B):

The product can be found as:

1. The $4$-aminobenzenesulpfonic acid is reacted with dil.$\mathrm{HCl}$ at low temperature to form diazonium salt.
2. The formed diazonium salt reacted with $\mathrm{N},\mathrm{N}$-dimethyl aniline to form the final coupling product.

Therefore, the above points and reaction diagram clearly explain the formation of final product.

(A) The above points and reaction diagram clearly explains that option A is incorrect.

(C) The above points and reaction diagram clearly explains that option C is incorrect.

(D) The A option is correct among the given options, hence option D is incorrect.
