(A) Violently rotating column of air
(C) Permanently frozen layer
(D) None of these
(B) Large system of winds
🧠 Explanation:
- A cyclone is a large-scale atmospheric system characterized by inward-spiraling winds around a low-pressure center.
- It can cover hundreds of kilometers and often brings heavy rain, strong winds, and storms.
- Unlike a tornado, which is a violently rotating column of air, a cyclone is much broader and lasts longer.
- Hence, the most accurate description is "large system of winds," making option (B) correct.
