Add "selected" attr to options in different select "tag"

I have one "table" with sizes. And want to add attr "selected" to "option" in all "selects in the document.

<select name="Size" id="size_11">
<option value="37" selected="">37</option>
<option value="37.5">37.5</option>
<option value="38">38.5</option>
<option value="39">39</option>
<option value="40">40</option>
<option value="40.5">40.5</option>
<option value="41">41</option>
<option value="41.5">41.5</option>
<option value="42">42</option>
<option value="43">43</option>
<option value="43.5">43.5</option>
<option value="44.5">44.5</option>
<option value="45">45</option>
<option value="45.5">45.5</option>
<option value="46">46</option>
<option value="46.5">46.5</option>
<option value="47">47</option>
<option value="48">48</option>
<option value="48.5">48.5</option>

This works:

$('#modal_sizes tr').click(function() {
$('option').removeAttr('selected').eq($(this).index()).attr('selected', ' ');

But it works only with the first "select" in the document Removing attr "selected" from all "option", but adding it only to an "option"s in first "select".


use option:nth-child in the selector

$('#modal_sizes tr').click(function() {
  $('select > option').removeAttr('selected');
  $('select > option:nth-child('+$(this).index()+')').attr('selected', ' ');
