Hi Anil, choosing a subject depends all upon you. What is your aim after you obtain the degree, what are your expectations with your degree and what your criteria are for the degree? The best we can do is to advise you on what the degree offers but choosing the degree is solely upon yourself and we can not make a decision for you.
