Hello Nandini,
If you do not want to continue with BA and want to pursue some other course instead, then you can either withdraw your admission or boycott the seat allotment in subsequent counselling rounds or if you have already provided the fee for that then the chances are that it will not be refunded in any case. So there is not mich problem to be faced if it is to be alloted through any counselling.
Hope it helped..
