Hi!
You should pursue masters in any of the subjects you had in your b.a. prog course. Admission in ma is done through entrance exams so it will be useful for you if you have previous knowledge in the subject you pursue.
(Aapko apne b a.prog ke kissi subject mein hi masters karna chahiye kyuki ma mein admission entrance exams se hota h toh apko easy hoga )

All the best!
