Dear Abhishek,
You can apply for MA in Hindi from JNU even if you had Pol science in your BA. As there is only one criterion for the admission that is you have to maintain the 10+2+3 academic pattern which means you don't have any backlog from your 10th to graduation plus you have to have 50% in your graduation. If you fulfill this criterion you can fill the form.
I hope this will help you.
Good luck
