Antarctica, Which Is Mostly Ice, Is Much Colder Than the Arctic

Antarctica, which is mostly ice, is much colder than the Arctic, which is a mixture of ice and water. Why?

A) The liquid water of the Arctic Ocean absorbs and releases a lot of heat that keeps the temperatures in that region from fluctuating.
B) The Arctic is much farther north than the Antarctic.
C) The salt in the water of the Antarctic keeps the water from freezing.
D) The specific heat of the ice is less than that of liquid water, which allows its temperature to change more readily.
E) Two of the above are reasonable.
