Biology

Medicine is found to be the most preferred option after +2 PCB with MBBS at the top of the list followed by BDS, BHMS, BAMS, BVSc, B.Sc Nursing, B.Sc Agriculture and Forestry. Food Science/Technology and so on. B.Sc in Science is also a preferred option. Biotechnology, Bio-Informatics, Nutrition and Dietetics, Home Science, etc., are also opted by many.

Yes, definitely you can pursue the course with biology in 10+2 provided that you are also having physics and maths as your subjects. The fact is that biology has no role to play in software engineering, so it is better to take computer science subject in 10+2. And maybe in some colleges, they prefer students with computer science for the course.
Thank you and best of luck.

You have to be student of PCM for science field.

You should go for B.Tech or MBBS since you have studied both maths and biology, LLB course would suit you well.
