Answer:
If I'm correct it should be B
Explanation:The correct answer is - B. Westerlies move warmer air toward the poles.
The Westerlies are winds that move from the lower latitudes (thus from the warmer areas) towards the bigger latitudes (south and north towards the poles). These winds move in a westward manner, and are the dominant winds between the latitudes of 30° and 60°. They have a global climatic effect. In the latitudes where they are the dominant winds, actually lives the biggest portion of the human population, which just proves there effect on the global climate, and we can comfortably state that it is a positive influence, at least for the human population.
