Hello Prema,
Don't go with someone else opinion. It's all upto you to choose your interest. If you are not aware of future careers opportunities then take help of your parents. Then decide which field excite you. Choose what you love.
Good Luck.

Your marks are good enough. But the actual question here is what you wanna do in life and what you want to become when you grow up. According to those, you need to pursue your career.
