D Correct answer
Explanation

This answer is correct and can be explained as follows: Sulphanillic acid contains SO3H and NH2 group. The SO3H group is capable of donating H+ and it acts as an arrhenius acid while nitrogen in NH2 group contains a lone pair of electrons and acts as a Lewis Base by donating it. Hence, sulphanillic acid is both an arrhenius acid and Lewis Base.
