Answer 1

Correct answer is D) A is acid but B is base

As substance A is sour in taste, we can say that it is an acid. Since it reacts with substance B to form salt and water, the reaction that is taking place here is a neutralisation reaction where an acid reacts with a base to form salt and water. Therefore, substance B has to be base.
