Let's say you had the following markup

  Volvo
  Saab
  Mercedes
  Audi

Using this jQuery, the saab option would be disabled.

$("select option").each(function() {
    var $thisOption = $(this);
    var valueToCompare = "saab";

    if($thisOption.val() == valueToCompare) {
        $thisOption.attr("disabled", "disabled");
    }
});
