How does marking a field as transient make it possible to serialise an object

Question

public class Foo implements java.io.Serializable {
   private int v1;
   private static double v2;
   private Loan v3 = new Loan();
}

Options:

Answer 1

Then how is transient in this case, helping us to serialize foo?

Because it allows you to serialize the rest of Foo, the other members that are serializable.
