I feel like it will display 11. The logic seems correct.

I feel like the program should run fine and display 11, but I can't shake the feeling that there's something wrong with the class B definition.

I remember something about templates needing to be defined correctly, so I'm leaning towards option B, that it won't compile.

I think the program will compile, but I'm not entirely sure about the template syntax.
