Wait, isn't Serializable an interface from Java I/O? Tricky question, but I'm guessing A is the correct answer.

That makes sense. A) The readExternal and writeExternal method it is.

Hmm, I'm going with C. Serialization is all about writing the object state to an output stream, so we only need to override the writeExternal method.
