Hello Aspirant

hope you are doing well and safe. With reference to your query,  I would glad inform you that you can go with any of the stream to be eligible for the civil services exam. But i would advise you to go for  science stream because the subject you will study in science like physics, chemistry will really improve your problem solving and thinking skills of brain and will improve your dedication skills as they require lot of hardwork to do

Hope you found this answer informative. Best wishes for your future
