A metal wire is stretched by a load. The force-extension graph is shown. What is represented by the area under the whole graph?

1. Athe change in gravitational potential energy of the wire
2. Bthe energy that would be released from the wire if the final load was removed
3. Cthe energy transferred into heat energy in the wire
4. Dthe work done in stretching the wire
