b. Why?

Answer 1

Hi - are you asking whether the implementation of this Class (A) conforms to best practices?

If so, well, there's not much here to comment on.

The code compiles successfully .... ;-))

It contains a default constructor, a destructor and a virtual function/method called fun() and no data members to speak of.

The dynamic fun() allows for dynamic binding across instances of A's sub-classes ...

But what else can we say? There's not much here.
