Hello Satendra,
In my opinion as much as I am knowing and understanding your thinking approach then you want to become a lawyer in future. But since you are already pursuing graduation I would suggest you to first complete it and then separately give entrance for only L.L.B. as now if you would go for B.A.L.L.B. then your very much precious time would be killed and wasted.
I hope my answer have helped you and hope you do well in future.
