B tech course No doubt, Unless You want to Go for Research in it. When You choose Computer Science and Engineering then Perhaps I think that You want to get Placed in Big MNC like Uber, Oracle. If You are in B tech then it will take only four Years for You to complete the Degree and Trust me companies Don't differentiate a B Tech and M tech unless You are interested in Hardcore Research which is even not the case with Computer science and Engineering, Therefor You can Compromise with college but not with B tech Never think for Dual Degree unless You want a full-time career in Resecrch.

Hello sanskriti ,
I suggest you to better choose btech computer science rather than mtech integrated,since if you preferred btech ,of branch computer science  you can learn the main basics such that it will be helpful in solving or analyzing big data or big queries
Else if you go for mtech integrated,all pin to pin basics are not very much clear ,they will be explaining with out any basic points ,it makes you to feel understandable ..
So better prefer btech,computer science .coding is the main current scenario currently moving on .so choose the best option
Good luck
