What I have tried:

Controller :-
------------

    return Json(ReportColumnsList, JsonRequestBehavior.AllowGet);
}

 $(document).ready(function () {
      $('#FavouriteReports').change(function () {
          $.ajax({
              type: "POST",
              url: '@Url.Action("GetColumnsByFavouriteReport", "MCPAdmin")',
              data: { Columns: $('#FavouriteReports').val() },
              datatype: "json",
              traditional: true,
              success: function (data) {

                  $('#SelectedFields').empty();
                  $.each(data, function (key, val) {
                      $('#SelectedFields').append('<option id="' + key + '">' + val + '</option>');

Use debugging (the "debugger" keyword) to examine "data" and "key" and "val". As your json is a list of objects then "val" will likely be an object too with properties so you're going to probably need to use "val.Something" rather than "val" when making your option. We don't know what properties are on "Report" so can't give you a concrete answer. But whatever property is on the object that you want to show in the dropdown is what you need to use, likewise for "key" if relevant.

check what value you are getting in console

success: function (data) {
console.log(data)
}
