It is just because of the top-down approach.

It is a top down approach. So derived class pointer cannot point to the base class.

Why D is not correct? Is we create pointer for base class?

There points and all the doubts will be cleared.
1) in top-down approach will can't do up casting where as reverse is possible.
2) As derived class has inherited there is no need for pointing to the base class object.
3) In top-down approach the derived class does not no about the base class do pointing to the base class is not possible using the pointer of derived class.

Then what is up casting?

Derived class is the class already inherited from base class. So, there is no need for derived class to point the base class. As I thought so.

@Deepak.
Take NO, C++ is OO language, so it has bottom-up approach, not top-bottom.

Being a static cast basic class have can assign base class pointer to derived class pointer.

Derive class is the derived one and there is no link with the base class there.

Derived class is a child class and base class is like parent to that.
