Suppose that a C++ class D is derived from a base class B. Class B has a public member function Func() that is declared to be virtual, and class D redefines its own version of Func(). At execution time, suppose that a D object is passed to the following function:

void DoSomething( B x )

{

x.Func();

}

Within the DoSomething function, whose version of Func() is called?
