Which fin type corresponds to an Air Inflatable Retarder?

Explanation:
Understanding fin types involves recognizing how the fin achieves drag or stability. An Air Inflatable Retarder is a fin design that inflates in flight to increase surface area and create extra drag, slowing the object down. In the list, the entry labeled Air Inflatable Retarder matches this design exactly. The other options describe rigid shapes (like conical or snake-eye fins) that do not inflate, so they aren’t the Air Inflatable Retarder. Therefore, the fin type is Air (Air Inflatable Retarder).
