Hii Rashi!
The subject you choose completely depends on your interest and choice of subjects. Look, what you find interesting to study or would want to study to gain some knowledge of that subject. You can go for economics, or entrepreneurship, which helps you with your main subject in future. Physical education will help you be fit and has its own subject knowledge. Computers is also a helpful subject. Else, go for what you find yourself interested in.
Hope this helps.
Good luck!
