Description:

The correct answer is:

Westerlies

The Westerlies are prevailing winds that blow from the west to the east in the mid-latitudes (between about 30° and 60° latitude in both hemispheres). These winds play a key role in weather patterns and storm movements across many populated regions, including North America and Europe.

Trade winds blow from the east to the west in the tropics (near the equator).

Polar easterlies blow from the east to the west near the poles.

So, the Westerlies are the correct answer for winds moving west to east in the mid-latitudes.
