Answer: None of the given option is correct

Explanation:

A serializable class is implemented, when an object is serializable interface. If you want to serialize one of your classes, then the class must implemented in the Serializable interface. To implement the serializable interface, convert a class into the series of bytes and when serializable object might reference your class. Serializable classes are useful when you wanted to persist cases of the class or send them over wire.
