What I have tried:

PageMethods.userlist($('option:selected', this).val(), function (result) {
           $("#UserList").empty();
           $("#UserList").append($("<option>" + 'select' + "<option/>"));
           for (i = 0; i < result.length; i++) {
               $("#UserList").append($("<option value=" + result[i].RC_UserID + "> " + result[i].Username + " </option>"));

           }
       });

correction

$("#UserList").append("<option>" + 'select' + "</option>");

end tag typo </option> not <option/>

follow this pattern to bind the items dynamically, since you are using jquery selector/append in the loop the performance will be low if the items length is more, for every item it will redraw the control items on the UI

var result = ['aaaa','bbbbb','ccccc']
           $("#UserList").empty();
           var html = ["<option>" + 'select' + "</option>"];
        for (i = 0; i < result.length; i++)
            html.push("<option value=" + result[i] + "> " + result[i] + " </option>");
        $("#UserList").html(html.join(''));
