My suggestion would be to choose a career that he is interested in and like to study more. Do not go by Job prospects, as nowadays, every good degree deserves a job in India, in the same field.
Choosing a career path, and sticking to it, is more important than just taking a course for the sake of job. Of course, everybody is looking for a job after studies. But, you can try to make it focused.
Of course, this is my suggestion or opinion, but the real thing lies in your Son's Decision and NOT in yours.
