Agreed. D is incorrect because the class should implement, not extend the interface.

I'm not sure. B and C seem wrong because the method isn't implemented properly.

Option D seems reasonable, but we need to actually provide the implementation of the pay method, not just declare it.

Haha, Option C is hilarious. Extending the PaymentProcessor interface? That's not how it works!
