I think, you should go for BBA or B.Com.

It depends on the specialization you wanna pursue in MBA

Any graduate is eligible for MBA admission because it is a generic or generalist degree. You can do any degree of your choice or interests. You may consider BBA, B.Com (Hons) , BA etc. Even B.Tech will be good.
