Selected data from the option tag to pass to Model C # - MVC

I'm developing an application with HTML and C # in MVC standards, and in one of the menus I need to put a list of options in which the user will select what they want, that data comes from the database, so what I did was as follows:

I created a Model and there I created a list.

public class NotasFiscaisModel
    {
        public virtual string usuarioLogado { get; set; }
        public virtual string dataUltimoLogin { get; set; }
        public virtual string unidadeInicio { get; set; }
        public virtual string unidadeFim { get; set; }
        public virtual string dataInicial { get; set; }
        public virtual string dataFinal { get; set; }
        public virtual string nome { get; set; }
        public virtual IList<NotasFiscaisModel> autorizados { get; set; }
    }

With this, I make a select to popular my authorized list

     foreach (DataRow linha in autoriz.RetornaAutorizados(LoginController._login.empresa).Rows)
  {
     NotasFiscaisModel nota = new NotasFiscaisModel();
     nota.nome = linha["nome"].ToString();
     _notas.autorizados.Add(nota);
  }

Inside the HTML, I have an excerpt that lists the options via tag option:

    <td>
      <div class="col-xs-2" style="width:190px">
           <div class="form-group">
              <select class="form-control" id="sel1">
              <option>Todos</option>
              @foreach (var obj in Model.autorizados)
              {
              <option>@obj.nome</option>
              }
              </select>
         </div>
     </div>
</td>

This works, as it shows what is happening in the print below (do not call pros values, it is test base kkk):

Now I would like to pick which user you selected, returning to my Model, making the Controller have access to that content and to be able to do more operations, is there a way?
