It's easy if you like Bio go ahead with Medical which ever line is available like mbbs or biotech or microbiology see these 3 courses have a lot of scope.

Future of agriculture depends on GMOs to provide us with a lot of food to be able to sustain the increasing population. Similarly with CRISPER technology being the new breakthrough in biology, Gene editing is also possible so a lot of scope in biology.

Now movie onto engineering fields if you are into what's inside a mobile.phone or how they work etc etc electronics hold a lot for you.

In chemistry you have chemical engineering it always holds a future later you can move into the food industry.

Physics you have theoretically physics.

In short there's plenty of opportunities. Don't let your 12th marks decide what u can and what you can't the skies the limit.
