# This is other quick option iterating options, counting the duplicates and remove when are more than one#

var opt = $("select[title='Country'] option");              
$.each(opt, function (key, value) {                 
  var len = $("select[title='Country'] option:contains(" + value.text + ")").length;
  if (len > 1)                   
     {
     value.remove();
     }   
  });
