Answer: D. A hurricane is a natural process, not the result of human activity.
Explanation: A hurricane is classified as a natural hazard because it is a natural phenomenon that occurs due to specific meteorological conditions, such as high ocean temperatures and specific wind patterns. It is not caused by human activity, unlike air pollution, acid rain, and ozone depletion, which are largely the result of human activities such as industrialization and deforestation. While hurricanes can vary in severity and destructiveness, and can cause significant damage across a wide area, it is ultimately the natural origin of the event that classifies it as a natural hazard.
