Wait, are we supposed to pay the exam question for processing too? I better bring some extra cash just in case.

Hmm, this question is a real 'pain in the payload' if you ask me. I hope the real exam isn't as tricky as this one!

Option C looks a bit suspicious. Extending the interface doesn't seem like the right approach here. We should be implementing the interface instead.

Option D seems to be the correct answer. We need to extend the PaymentProcessor interface and provide the implementation for the pay method.

I'm not sure about option B. Declaring the pay method without an implementation doesn't seem right. Shouldn't we have the method body as well?
