Will this dynamic_cast work

Consider following use of C++ dynamic_cast:

struct A
{
    virtual void Foo() { std::cout << "A"; }
};
struct B : public A
{
    void Foo() { std::cout << "B"; }
};

A* aPtr = new A();
B* bPtr = dynamic_cast<B*>(aPtr);

Select the appropriate outcome of above dynamic_cast operation from given choices:
