hello bhupesh 

doing bsc from any one of the subjects you have mentioned gives nearly equal  opportunities to you. i think you should chose the courses in which you are interested most as most of the students prefer higher education after bsc which recquires greater interest . however if you are just job oriented then maths honours would be best then chemistry and later physics .(according to my view)feel free to ask in the comments below best wishes 

Hello Aspirant, It is depend on your interest if like Physics then go for physics. But I suggest you that you have to take Mathematics because it has more scope other than two. If you want to for Multinational  company they use Applied Mathematics. 

I hope this will help you.
