Hold on, the question says to use the 'expected output', so I'm guessing we need to call the print() method of the derived class B. Option C for the win!

Wait, aren't we supposed to use the scope resolution operator to access the print() method of A? I'm leaning towards option B.

But if you look at the image, it clearly shows that ob2 is an object of class A, so A) ob2.A::print() makes more sense

Hmm, looks like we need to call the print() method of the base class A, not B. I think option A is the way to go.
