I do not know if it's the best implementation, but you can solve your problem by changing its function like this:

function passar() {
   var valorA = document.getElementById("valorA");
   var nome = document.getElementById("nome");

   for(var i = 0; i <= valorA.options.length; i++) { //itero em cada option
     nome.value += (valorA.options[i].value + '\n'); //seto o (value|text) no textarea com uma quebra de linha
   }    
};

Follow jsfiddle :)

And to pass the option selected, you can simply do this:

function passar() {
    var valorA = document.getElementById("valorA");
    var nome = document.getElementById("nome");

    nome.value += (valorA.value + '\n'); //Acessa diretamente o value do select que já é o elemento selecionado
};

Follow the jsfiddle :)
