Hmm, I'm leaning towards option D. If we're using JPA entities as parameters or return values for remote EJB operations, then we should definitely implement Serializable, right? Gotta keep that data transfer secure!

I'm not so sure about that. I've used JPA entities without implementing Serializable before, and it seemed to work fine. Maybe option B is the right choice?
