Dear aspirant,
Among the options mentioned by you it is better to choose B.Sc + M.Sc Biotechnology Integrated Course from Vellore Institute of Technology as you are interested in doing research work. After completing this integrated course you can pursue Ph.D for further reasearch. You can complete B.Sc and M.Sc at one place from same college. There will be good career opportunities for students in this field. Now it's your choice to take the decision.
Hope this helps.
All The Best!!
