A metal wire hangs from a support, and loads with different masses are hung from its lower end. The table shows how the extension of the wire changes with the mass of the load. Between which values of mass does the limit of proportionality lie?
- A0 and $2.0\,\text{kg}$
- B$4.0\,\text{kg}$ and $6.0\,\text{kg}$
- C$6.0\,\text{kg}$ and $8.0\,\text{kg}$
- D$8.0\,\text{kg}$ and $10.0\,\text{kg}$
