I think you need to decide what you like for yourself - nobody can make that decision for you. Make a list of things that you would want to possess at the end of 4 years of B.Tech: skills, a well paying job etc. If you don't go beyond and work very hard, you will mostly end up in an IT company regardless of your degree(which wouldn't matter much there unless it's CS). So if you are just interested in getting a job in an IT company(like CTS, Infosys or TCS), settle for CS since you'll learn something relevant to the job you target.

Both cse or cse artificial intelligence are very good.It depends on your interest.Scope for placements are the same.

Choose wisely!Cheers!
