The correct response is:

**The metal’s molecules are moving around.**

Even though the metal sphere is stationary as a whole, the individual atoms and molecules within it are still in motion due to thermal energy, which contributes to its internal energy. This motion is not the same as kinetic energy in the context of macroscopic motion, but it still involves motion at the microscopic level.
