How does the addition of salt to solid ice affect the melting transition from solid to liquid?

Graph showing time on the x axis and temperature on the y axis. Graph starts on the bottom left as a solid, and slopes up to the right. Before becoming a liquid the graph plateaus showing no increase in temperature, then becomes a liquid. The graph then slopes up to the right towards gas. Before becoming a gas, the graph plateaus again showing no increase in temperature while changing into a gas.



A. The amount of energy absorbed would not change during the plateau.
B. It would need to absorb more energy during the plateau in order to melt.
C. There would be no plateau, the salt would cause the solid to immediately melt.
D. It would need to absorb less energy during the plateau in order to melt.
