Which career option is better among doctor and lawyer? My favorite subjects are maths and science.

While it is a personal choice, it would be best to seek career counselling and guidance professionally. Also, because the choice of subjects is pretty fluid, it may change over a few months, so take an informed decision. For example, you may have grade 10th maths, but grade 12th maths is very differ

There is no better career option per se. It is largely dependent on your interest. Your favourite subjects suggest that you are more inclined towards Science and it will be better if you pursue your goals as per your interest.
