Prathibha it all depends on your interest, in which field you want to grow yourself and build up your career because both the courses are equally good but both of them are the totally different field.

By doing engineering i.e. BE/B.tech in Computer science will open a lot of job opportunities for you in the future as we are enhancing towards a completely digital world and even in today's almost all the work involves internet, computer and coding so by doing engineering no doubt there will be a lot of scope for you in future.

Now BBA+MBA will take you into the totally different field of management in the corporate world which again has never-ending opportunities because irrespective of the field every company requires employees who are experts in management without them none of the company can work efficiently. In MBA field you will have lots of streams in which you can do specialization like MArketing, Finance, Operations, Strategic, Human Resource etc.

So, in the end, you need to choose whether you want to go for management field or technical field of computer science. Both are good streams, make a decision on the basis of your interest. If say you have interest in both the fields then you can also do B.E/B.Tech in Computer science first then in your post graduation you can do MBA in IT field. This will enhance your skills furthermore.

Feel free to ask if you have any more queries. All the best!!
