Selected Combox in javascript

Navigation

Good evening guys, I need some help, it's simple but I'm curled up. I have this combo inside a MODAL, it happens that the fields of this modal I populate everything by javascript / Json searching the data of a database.

MODAL 

<!-- Grid column -->
<div class="col-lg-4 col-md-4">                                     
   <div class="md-form form-sm">
      <select class="mdb-select colorful-select dropdown-primary" searchable="Busca por nível.." id="frmnivelacesso">
         <option value="1"> Master</option>
         <option value="2"> Secretária/Recepcionista</option>
         <option value="3"> Cirurgião Dentista</option>
      </select>
      <label for="form8" class="">Nivel de acesso</label>
   </div>
</div>
<!-- Grid column -->

JAVASCRIPT 

$("#ModalUsuarioEdit").on('shown.bs.modal', function(){

        var id = $('#ModalUsuarioEdit').data('id'); 
        $.post('estrutura/usuario.php',{acao:'select',id:id},function(r) { 
               var ev = jQuery.parseJSON(r);           
               if (ev.success) {


                    document.getElementById('frm-imgname').src = 'arquivos/images/' + ev.foto;
                    var nomecompleto = ev.nome + ' ' + ev.sobrenome;
                    $("#frm-username").text(nomecompleto);

                    $("#frmnome").val(ev.nome);  
                    $("#frmsobrenome").val(ev.sobrenome); 
                    $("#frmdtnascimento").val(ev.nascimento); 
                    $("#frmcargo").val(ev.cargo); 
                    $("#frmemail").val(ev.email); 
                    $("#frmtelefone").val(ev.telefone); 
                    $("#frmcro").val(ev.cro); 
                    $("#frmusuario").val(ev.usuario); 
                    $("#frmsenha").val(ev.senha); 

                    $("#frmnivelacesso").val(ev.nivel); // nesse ponto não sei como fazer com que a option da combo fique seleciona 

                    $("#frmnome").focus();
                    $("#frmsobrenome").focus();
                    $("#frmdtnascimento").focus();
                    $("#frmcargo").focus();
                    $("#frmemail").focus();
                    $("#frmtelefone").focus();
                    $("#frmcro").focus();
                    $("#frmusuario").focus();
                    $("#frmsenha").focus();
                    $("#btnfechar").focus();

               }         
        });

You select option by value ( .val() ), selecting select by id , like this: 

$("#frmnivelacesso").val(ev.nivel);

Example: 

var ev = { nivel: 2 }
$("#frmnivelacesso").val(ev.nivel);
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script><!--Gridcolumn--><divclass="col-lg-4 col-md-4">                                     
   <div class="md-form form-sm">
      <select class="mdb-select colorful-select dropdown-primary" searchable="Busca por nível.." id="frmnivelacesso">
         <option value="1"> Master</option>
         <option value="2"> Secretária/Recepcionista</option>
         <option value="3"> Cirurgião Dentista</option>
      </select>
      <label for="form8" class="">Nivel de acesso</label>
   </div>
</div>
<!-- Grid column -->

Or using the .prop() method: 

var ev = { nivel: 3 }
$("#frmnivelacesso option[value='"+ev.nivel+"']").prop("selected", true);
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script><!--Gridcolumn--><divclass="col-lg-4 col-md-4">                                     
   <div class="md-form form-sm">
      <select class="mdb-select colorful-select dropdown-primary" searchable="Busca por nível.." id="frmnivelacesso">
         <option value="1"> Master</option>
         <option value="2"> Secretária/Recepcionista</option>
         <option value="3"> Cirurgião Dentista</option>
      </select>
      <label for="form8" class="">Nivel de acesso</label>
   </div>
</div>
<!-- Grid column -->
