Hello..

Your question is bit unclear since you have not mentioned any thing in detail. You can see below for more info:

I guess you are from J&K. 
RBA or Resident of Backward Area is given reservation in J&K only. In NEET, there is no such option. If you belong to J&K, fill the NEET form as General category. Later, at the time of counselling, mention your category as RBA to avail the benefits.
