Best answer
Correct choice is (a) Yellow

For explanation: Diazonium salts on reaction with aniline form azo compounds which are coloured. This is because of the complex system involving the N-N double bond between two aromatic rings. In this case, compound A is p-aminobenzene, which is yellow coloured.
