The mercury in old thermometers has a Melting point of -38.8 °C. The correct answer is C.

Its melting point equals -38.8 °C because it is mercury.

The melting point of a substance refers to the temperature at which it changes from a solid to a liquid state.

In this case, the mercury in old thermometers has a melting point of -38.8 °C.

This means that when the temperature of the mercury reaches -38.8 °C, it will start to melt and turn into a liquid.

Since the question states that the mercury in the photo has a melting point of -38.8 °C, we can conclude that the melting point of the mercury in old thermometers is -38.8 °C.

Option C is the correct answer.
