Answer: Option D

Solution(By Examveda Team)

The temperature decreases towards poles, because the sun rays falling per unit area are less at poles. The amount of insolation received on the earth’s surface is not uniform everywhere. It varies according to the place and time. When the tropical regions receive maximum annual insolation, it gradually decreases towards the poles. Insolation is more in summers and less in winters.
