There are 2 answers. A. At J, the wire becomes plastic: This is correct. The yield point (J) marks the transition from elastic to plastic deformation.
B. J is the yield point: This is also correct.
C. L is the elastic limit: This is incorrect. L is the fracture point. The elastic limit is typically near the end of the linear portion, before J.
D. At K, the wire breaks: This is incorrect. K is the ultimate tensile strength. The wire breaks at L.
