The correct response is:

Yes, they stop when they reach absolute zero.

At absolute zero (0 Kelvin or -273.15 degrees Celsius), the thermal motion of molecules is minimal, and they theoretically stop moving. However, in reality, reaching absolute zero is impossible according to the third law of thermodynamics.
