In order to write objects to an ObjectOutputStream, the class needs to implement the Serializable interface. This allows the instance variables to be written to a stream and then re-constructed when read back in. Option A is not necessary as non-primitive instance variables can still be serialized, and Option B is not a standard Java interface. Option C is not necessary if the class implements Serializable, as ObjectOutputStream can automatically write the object's state to the stream.
