Ian left a cup of hot chocolate in a cool room. His mother tells him that his hot chocolate will get cold if he forgets to drink it. How cold could it get?

Colder than the temperature of the room. It will keep cooling down for as long as he leaves it in the room.

Only a little colder. It started out much hotter, so it will stop cooling down before it reaches the same temperature of the room.

Only a little colder. It will stop cooling down when its temperature is about halfway between its starting temperature and the temperature of the room

Only as cold as the temperature of the room. It will stop cooling down when it is exactly the same temperature as the room.

Although it will still cool very slightly due to evaporation, room temperature is the reasonable answer.
