The Loan class given in the text does not implement java.io.Serializable. Analyze the following code.
``` public class Foo implements java.io.Serializable { private int v1; private static double v2; private Loan v3 = new Loan(); } ``` a. An instance of Foo can be serialized because Foo implements Serializable. b. An instance of Foo cannot be serialized because Foo contains a non-serializable instance variable v3. c. If you mark v3 as transient, an instance of Foo is serializable. Key:bc An object may not be serialized even though its class implements java.io.Serializable, because it may contain non-serializable instance variables.
