Just use removeAttr() for all options:

 $('#rating option').removeAttr('selected'); console.log($('#rating').html());

 <script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script> <select name="rating" id="rating" required=""> <option value="0" selected="selected">رای دهید</option> <option value="5" selected="selected">عالی</option> <option value="4" selected="selected">خوب</option> <option value="3">متوسط</option> <option value="2" selected="selected">نه خیلی بد</option> <option value="1">خیلی بد</option> </select>
