    you said c, but the answer refrigerator is answer b.

    Refrigerators remove heat from the inside of it and pump it to the outside of it, the inside is usually cooler, so when you put your leftovers in it, the fridge pumps the heat from the food out of the 'cool' part (the inside of it) and takes it to the outside of it (the warm part).
