Hi,

Well you need to fill the category that you fall in nationally. Also since your domiciled state is chattisgarh and you don't fall under the category of obc in state so I think you will fall under the general category nationally as well. Cause you can't have benefits of two state counseling seats as you can only avail the benefits of state quota seats from your domiciled state. And that too may decide your category.

I hope this helps.

All the best.
