This is a piece of cake! Option A is the way to go. It's like paying with a check - you gotta fill out the details, right?

Options C and D seem to be incorrect. The `CheckPaymentProcessor` class should implement the `PaymentProcessor` interface, not extend it.

Hmm, option B looks a bit strange. Shouldn't the method body be implemented in the class that implements the interface? This is not a valid implementation.
