Assuming that the serializeBanana2（） and the deserializeBanana2（） methods will correctly use Java serialization and given： 
import java.io.*； 
class Food {Food（） { System.out.print（”1”）； } } 
class Fruit extends Food implements Serializable { 
Fruit（） { System.out.print（”2”）； } } 
public class Banana2 extends Fruit { int size = 42； 
public static void main（String [] args） { 
Banana2 b = new Banana2（）； 
b.serializeBanana2（b）； // assume correct serialization 
b = b.deserializeBanana2（b）； // assume correct 
System.out.println（” restored “+ b.size + “ “）； } 
// more Banana2 methods 
} 
What is the result？（） 

A .  Compilation fails.
B .  1 restored 42
C .  12 restored 42
D .  121 restored 42
E .  1212 restored 42
F .  An exception is thrown at runtime.
