Correct Answer: B
To implement the java.io.Serializable interface to the MyPersistenceData class, you don't need to override any methods. The Serializable interface is a marker interface, which means it does not declare any methods that need to be implemented. It simply marks the class as being serializable, meaning its objects can be converted into a byte stream and subsequently restored. Therefore, the correct option is B.
