C Correct answer
Explanation

 The source of tropical cyclones occurrence lies between 5° to 30° latitudes in both the hemispheres. They never form exactly over the equator. A tropical hurricane is nearly circular vortex averting 500 to 600 km in diameter. The diameter of small sized Tornado violent storm varies from 150 to 600 meters. Hurricanes form only over oceans having a high surface temperature (27°C). Whenever a tropical cyclone moves on to land, much of its severity is reduced simply because its source of moisture is cut off. In other words, no energy is available on land to maintain a cyclone. The weakening of the hurricane over land is also the result of increased friction.
