Which direction does air flow within a cyclone?

a. Air rises.

b. Air sinks.

c. Air flows laterally.

d. Air does not move in a cyclone.

I think the correct answer from the choices listed above is option A. The direction of the air flow within a cyclone would be up. The air would rise up. A cyclone is an air mass that rotates around a center which has low atmospheric pressure. Hope this answers the question.
