Wait, can you use two namespaces like that?

I'm leaning towards option B, but I have a nagging feeling that we might need something from the second namespace too.

I feel like using just one namespace could lead to conflicts, so maybe option C is the way to go?

I remember practicing a similar question where we had to choose the right namespace, but I can't recall if we needed both or just one.

I think option A might be correct since it includes both namespaces, but I'm not entirely sure if that's necessary.

This is a good opportunity to apply my understanding of namespaces. I'll carefully consider each option and try to eliminate the incorrect ones.

I'm feeling pretty confident about this one. Namespace usage is something I've practiced a lot, so I should be able to work through this step-by-step.

Okay, I think I've got this. The key is to figure out which namespace contains the variables or functions needed to produce the expected output.

Hmm, I'm a bit confused by the different namespaces here. I'll need to review my notes on using namespaces properly in C++.

This looks like a tricky namespace question. I'll need to carefully read through the code and think about how the different namespaces are being used.

Hmm, this seems a bit tricky. I'm not entirely sure how the gotoPriorityExpression values affect the evaluation order. I'll need to re-read the question and the policy details carefully.

Overlapping trust boundaries sounded familiar, but I can't quite remember how it applies to data threats.

I'm not totally sure about this one. I know synchronous and asynchronous have to do with how the API calls are handled, but I'm not confident I can identify the right characteristic. I'll have to think it through carefully.

I think the key here is that the solution components are being assembled and constructed in direct response to a set of requirements. That points to "Design" as the best answer.

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

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
