Final answer:
Wind is the correct term for the flow of air masses from high pressure to low pressure areas, not to be confused with convection, hurricanes, or climate.
Step-by-step explanation:
In response to the question about how air masses flow from areas of high pressure to areas of low pressure, the correct option is C. Wind. Wind is produced as air moves from high-pressure areas to low pressure areas. This movement of air is a result of the differences in atmospheric pressure, causing the air to flow, which we perceive as wind.
In contrast, convection refers to the heat transfer by the macroscopic movement of a fluid which can involve the flow of air due to temperature differences, but is not the direct flow from high to low pressure areas. A hurricane is a specific type of storm with high winds, but not a general term for the flow of air masses. Climate refers to weather patterns in a region over a long period, again, not the direct flow of air from high to low pressure.
