What can you afford to pay? Have you run the NPC on some top schools to see what they say?
Depending upon your budget, there might not be any safeties in North America (in the sense of being safe both for admissions and for affordability).
You are obviously competitive anywhere. You will have some chance at top schools. However, the universities in the US which provide full financial aid for international students are few in number and very, very competitive for admissions. They get a lot of applications from excellent Indian students such as yourself.
One wild idea: This would also be a reach, but you might consider applying for the Lester B Pearson scholarship at the University of Toronto. It is very competitive. You would need to get your high school to sponsor you to even apply. However, if you get it then you would have a great scholarship at an academically excellent university with really strong CS and bio-engineering programs. I do not know anything about its business program but it is a very strong university in many, many ways.
A bachelor’s degree in India plus a master’s degree in North America might be less expensive and is also something to consider. Even financing a one year master’s degree is however not cheap.
I hope that you have recovered well from your health issue. To me your ECs look very good. I am impressed by your strengths and I expect you to do well wherever you end up.
