The correct answer is D. Wax

Step-by-step explanation:

In chemistry, the melting point of materials or substances refers to the temperature at which a material changes from the solid state to a liquid state which varies according to each material. In the case of wax, its melting point is around 46°C and 68°C which is lower than other materials such as metals that have a melting point between250°C to more than 1000°C depending on the metal or clay that has a melting point around 1780°C. This makes wax one of the materials with the lowest melting point and therefore, one of the most useful materials for making molds.
