Option 1 states that a cyclone is a wind circulation system with low pressure at the center. This statement is correct. Cyclones are characterized by a rotating, organized system of clouds and thunderstorms, with a center of low atmospheric pressure.

Option 2 states that a cyclone brings about sudden changes in weather conditions in an area. This statement is correct as well. Cyclones are often associated with heavy rainfall, strong winds, and can cause significant damage to infrastructure and agriculture.

Option 3 states that wind movement towards the low-pressure center of a cyclone is clockwise in the northern hemisphere. This statement is incorrect. In the northern hemisphere, the wind movement towards the center of a cyclone is actually counterclockwise. It is the opposite in the southern hemisphere, where the wind movement is clockwise.

Option 4 states that a cyclone is known as a hurricane in the West Indies. This statement is correct. Cyclones are known as hurricanes in the North Atlantic Ocean and the Northeast Pacific Ocean. In other regions, cyclones are known by different names, such as typhoons in the Northwest Pacific Ocean and tropical cyclones in the Indian Ocean.

In summary, option 3 is the incorrect statement as wind movement towards the low-pressure center of a cyclone
