Hello Aspirant,
As you have mentioned that you are from Jammu and Kashmir and you have passed only class 12th from Rajasthan so to get admission under Rajasthan domicile you must have been the resident of Rajasthan for at least 10 years but you do not fulfil this so you have to register for CSAB Counselling under J&K domicile only. So you should submit the state of eligibility for Jammu & Kashmir.
For complete details about CSAB Counselling kindly check out the link given below :-

I hope this information helps you.
Good Luck!!
