Which course should I pursue among B.Tech and BBA to become an entrepreneur? Shall I pursue MBA afterwards?

If you set your mind for become an entrepreneur then go for BBA after that MBA. Good luck !!

if you are willing to start your business in any IT industry, I will prefer doing b-tech that too in IT or CS. and if your area of interest in outside IT. you can opt for BBA. Good Luck.

I strongly recommended you to opt for BBA if you want to be in entrepreneurship ,instead of b.tech ,because doing MBA after BBA is quite better than b.tech. doing b.tech will be just wasting time and money because in future it will of useless
