I wonder if the expected output involves a surprise dance party. If so, I'm going with option B --> A::print(); *dances awkwardly*

User 3: I agree with Carolynn, option A) ob2.A::print(); seems like the right choice.

This is a real head-scratcher. I'm just going to flip a coin and hope for the best. *flips coin* Aha, option D it is!

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!

Let's go with option C then, it seems to be the most logical choice.

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.
