The first major rock edict of Ashoka deals with —

The correct answer is Condemnation of animal sacrifice. Major Rock Edict I restricts animal slaughter and condemns sacrificial killing and certain festive practices. Edict II covers medical welfare, III official tours and V the Dhamma Mahamatras. A strong answer should connect the term or object with its precise source, location, ruler, regnal context, and administrative function. Similar-looking options often belong to a different edict, institution, dynasty, religious tradition, or chronological phase. Reading the wording closely is therefore essential, especially when the question uses expressions such as ‘according to the Arthashastra’, ‘major rock edict’, ‘traditionally associated’, or ‘first used widely’.
