Yes, A.
Now wait a minute, of course it is A. Think about air warming and rising and new air coming inward underneath and air coming from the south going east fast with the earth but the earth moving slower under it as it goes north because we are getting closer to the axis of rotation and therefore that air getting east of the hot spot and similarly the air moving south toward the hot spot ending up west and that being a rotation that gets faster and faster as the air from all sides approaches the center . Whooosh !
