Hey student,

Christians can claim OBC and ST reservation. Only followers of Dharmic religion claim SC reservation.

So, I think you should opt for OBC category in NET UC.

For more details on Reservation categories, you can check their official website or this link:

All the best student,

Hope this helps you.
