3. public int x, y;
4. public Foo( int x, int y) { this.x = x; this.y = y; }
5.
6. private void writeObject( ObjectOutputStream s)
7. throws IOException {
8. s.writeInt(x); s.writeInt(y)
9. }

Which code, inserted at line 14, will allow this class to correctly serialize and deserialize?()
A . s.defaultReadObject();
B . this = s.defaultReadObject();
C . y = s.readInt(); x = s.readInt();
D . x = s.readInt(); y = s.readInt();
