The extension of a spring is measured for various loads. The limit of proportionality is not reached. Which graph shows the extension–load graph for the spring?

1. Aextension–load graph: straight line from positive extension intercept at zero load, decreasing to zero extension at positive load
2. Bextension–load graph: straight line from origin with positive gradient
3. Cextension–load graph: curve from origin with decreasing positive gradient
4. Dextension–load graph: curve from origin with increasing positive gradient
