Answer: The answer is C. Minimal variation in solar isolation and low sun angles
Explanation: Polar regions are located in the north end and south end of the globe: the two pole ends of the Earth. The northern polar region is called the Arctic, and in the southern polar region is the continent of Antarctica. Polar regions have very low temperature and very long winter as a result of being farthest from the equator, hence, they receive the least amount of sunlight and the sun's energy arrives at an oblique angle.
