Hey Sannat.

You cannot apply for Law in DU right after 12th class. As DU offers only a 3 year LLB course and the minimum eligiblity criteria for a 3 year LLB course is undergraduate degree. So if you want to do LAW after 12th directly then you will have to look for entrances and colleges that offer 5 year Integrated course of law like CLAT, AILET, IPU CET, PU, SLAT etc
