Answer

Option 1.

Change in your RoleList function.In the above function the role name is assign RoleName variable and get Name only which is not variable name in the function.

      public static IEnumerable<SelectListItem> RoleList()

        {
         
            SMSEntities _ent = new SMSEntities();
            var data = (from a in _ent.AspNetRoles
                        where a.Name!="SuperAdmin"
                        select new
                        {
                            RoleName = a.Name,
                        }).ToList();
            return new SelectList(data, "RoleName", "RoleName");
        }
