I assume that the correct syntax for the getClassById is
Object getClassById(uint id) {
     if (id == 0) {
         return new A();
     } else if (id == 1) {
         return new B();
     } else {
         return new C();
     }
}
or maybe I'm wrong.

If the constructor has no parameters, classes can be new'd without 
parentheses, so your modification results in identical code as my example.
