Answer: B. The regions near the poles get the most-intense sunlight
Explanation:
The regions by the poles get the least sunlight with the Equator receiving the most direct radiation from the sun. This then spreads out as it approaches the poles due to the curve of the Earth.
This is why areas like Greenland and Antarctica which are closer to the poles are colder because there is less sunlight to melt them.
