All suggested me almost the same criteria for selection.
1. Background Knowledge
2. Connection b/w subjects
3. Interest

So as I am going to opt IR. With it I will opt I. LAW and USA history. It all makes 400 numbers. Now I have done MBA so I am going for Business Adm and finally I had to select last subject. After reading past papers of three years of Sociology, Journalism and Gender Studies I found out Sociology is suitable for me which brings it to completion of my selection.

Best of luck to all of You.
