You have to use $('#sela>option[value = ' + x + ']') to select the direct option child of #sela.

And use text() to update the option text.

var x = 2
var str = 'earth';

$('button').on('click', function() {
  $('#sela>option[value = ' + x + ']').text(str);
});
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>

<select id='sela'>
  <option value=1>lorem</option>
  <option value=2>ipsum</option>
</select>
<br><br>
<button>CLICK</button>
