BCA

Both have their own advantages. I think you must go for BCA because in it you can explore more things rather than just focusing on AI and ML. B.Sc. in AI and ML
The programme will help candidates:
To understand, evaluate and analyze the history of Artificial Intelligence. To identify those areas of the domain which are yet to be explored. To apply basic principles of AI in solutions that require problem-solving, inference, perception, knowledge representation, and learning. To become proficient in developing applications in an 'AI language', expert system shell, or data mining tool. To gain the ability to explore the current scope and limitations, and societal implications of the domain. BCA full form Bachelor of Computer Application is a 3-year undergraduate course that imparts knowledge on the basics of computer application and software development. BCA subjects include database management systems, software engineering, operating systems, web technology, and computer languages such as HTML, C, C+, and Java.

BCA is a blend of Science, Commerce, Management Studies & Computer Science. It helps you holistically, hence, opening up opportunities for a lot of industries.

Which course you want to pursue that totally depends on what you wanna do after graduation. I mean if you want to work for a company as a developer then you should opt for BCA but if you want to be a professor then B.Sc. Is a good option for you. It doesn't mean that you cannot work for any company after B.Sc. But you have to work harder than others. The reason why I am telling you is that in B.Sc. The focus is on theoretical knowledge rather than BCA where you will learn about applications. Below are some of the best Private Universities:-
BITS Pilani, ICT Mumbai, Mumbai. VIT Vellore, Vellore. Thapar Institute of Engineering and Technology - [TIET], Patiala. ITER Bhubaneswar, Bhubaneswar. LDCE Ahmedabad - LD College of Engineering. Geeta University, Panipat
