Hmm, I'm not sure about this one. I think option B might be correct, but I'm a bit skeptical about the use of the lambda expression.

I'm not sure, but I think D is the correct answer because the Moveable interface cannot be used in a lambda expression.

Wow, this question is really testing our understanding of interfaces and lambda expressions! I'm leaning towards option A, since it seems to be the only one that correctly uses the interface and lambda syntax.

I disagree, I believe the correct answer is C because it includes the correct syntax for using the Moveable interface with an Integer parameter.
