Hey,

B.A or bachelor of Arts is a 3 years graduation course in which you have liberty to choose any of the subject from arts faculty ( philosophy, English, linguistics, geography, economics, political science, history, sociology, etc.)

As per your query, you said that you want to do B.Ed in future. So, its pretty clear that its better to select the subject in which you have interest and which you can teach well.

I hope this will help you.
