Hi Anuradha!

Since you are asking about the same college itself, you can confidently choose a course which interests you the most. You need to think whether you would be happy with what you took 10 years down the line when your pursue the career. All of these have scope and finding jobs would not be a problem if you study well. It is also more like choosing between Chemistry, Botany and Zoology so you can choose according to the subject of maximum interest.

All the best!
