You should not choose your career option according to just in which field there are more income. You should choose your career option in which field you have lots of interest otherwise it will be difficult for you to work in that field in which you don't have any interest.

If you are good enough in any field then you will learn lots of money in that field but if you go without interest in any field then you will not be successful and you will not be able to earn money.

If you are really thinking in terms of money than I will suggest you to go for MBA from top institutions like IIMs then it will be best for you but for the same you have to really work hard to get into a good b-school like the IIMs in india.
