Wait, isn't C just wrong? You can't extend an interface!

I’m leaning towards option D because it has the method implemented, but I’m confused about the use of 'extends' instead of 'implements'.

I feel like option C is wrong since you can't extend an interface directly. It should be implementing it instead.

I'm not entirely sure, but I remember something about abstract methods needing to be implemented. Maybe option B is right?

I remember practicing a question like this where the dual stack approach was highlighted as common. Based on that, I'd lean towards "C," but I'm still second-guessing myself.
