Hi Aman,
It's totally up to you to choose your stream. It's on your interest. Otherwise, go for B.Arch as there is more scope as less people pursue it as compared to B.Tech.

All of the guys answering here about B.Sc IT and B.Tech are mostly from the so commonly degree called B.Tech. So it's obvious that they will all favor B.Tech and discourage B.Sc IT. But let me tell you one thing there is no such difference between both of these, the difference just lies in the mentality of folks who are answering here.
If you have a good knowledge of database, software and programming languages, then there is a lot scope of getting a high paying job in IT industry and a B.Sc IT degree with great depth of knowledge is preferred over the copy paste studies of B.Tech students who just have a degree, no understanding.
