The correct answer is:
**a** When it has reached the same temperature as the room temperature air.
Heat transfer will stop when both the cup of coffee and the surrounding air reach thermal equilibrium, meaning they are at the same temperature. At that point, there is no longer a temperature difference to drive the transfer of heat.
