Answer:
b. clockwise; counter-clockwise
Explanation:
The Coriolis force diverts these winds from the Northern Hemisphere to the right and from the Southern Hemisphere to the south.
Throughout the Northern Hemisphere, this deflection allows the wind to circulate across clockwise direction around tight-pressure systems while moving in counterclockwise direction around low-pressure systems.
Due to the Coriolis effect, low pressure systems in the northern hemisphere spin clockwise and in the southern hemisphere they spin counter clockwise.
