Compressive forces are applied normally to the end faces of a cylinder of initial length L. The cylinder is compressed by the forces so that its length decreases to 0.6L. After the compressive forces are removed, the cylinder's length increases to 0.8L. What describes the deformation of the cylinder when its length was 0.6L?

1. Aboth elastic and plastic
2. Belastic only
3. Cplastic only
4. Dneither elastic nor plastic
