C. Horse Latitudes

Explanation:

The "horse latitude" is an area located on the north and south of the tropics–30 degrees north of the equator and 30 degrees south of the equator. The wind in this area separates into different directions; thus resulting to a narrow band of windless area or calm wind. It is also characterized by sunny, clear skies and little to no precipitation.

The term was derived from a historical event during the opening of the New World. Many people transported horses via ships. When they reached this windless area, they had a hard time sailing towards their destination. So, what they did was to throw the horses into the sea to make their ships lighter.
