Final answer:
The Correct option is 1). Ernest's Emergency Supplies uses geographic segmentation by marketing its products in regions susceptible to hurricanes and tropical storms, targeting demographics that need such emergency supplies.
Step-by-step explanation:
The example provided where Ernest's Emergency Supplies markets its products specifically in areas along the Gulf Coast of Florida is an example of geographic segmentation. Geographic segmentation is a marketing strategy where a business divides its market based on location, such as countries, regions, cities, or neighborhoods. By targeting areas prone to hurricanes and tropical storms, the company ensures that its emergency supplies are marketed to populations that are more likely to need them due to these frequent natural occurrences.
