Your HTML is invalid. You need to close <option>
tag using </option>
You also need to give different value beside 1
such as -1
or leave it as blank for the first option inside each of your select
Then you can do like this to achieve your requirements:
$('select').change(function () {
var selectedVal = $(this).val();
$(this).siblings('select').find('option[value="' + selectedVal + '"]').hide();
$(this).siblings('select').find(':not(option[value="' + selectedVal + '"])').show();
$(this).siblings('select').find('option:eq(0)').prop('selected', true);
});
