Solution

The correct option is A
melting point

The change from the solid state to the liquid state on heating at a fixed temperature is called melting.

The temperature at which a solid gets converted into its liquid state without further increase in temperature is called its melting point.For example, ice(solid) at $0^{\circ} C$ melts to form water(liquid) at $0^{\circ} C$ by the absorption of heat.
