Final answer:
Dry cleaners represent a bulk-gaining industry and benefit the most from being close to their market due to the nature of their services and customer interaction needs.
Step-by-step explanation:
The type of company that would be most interested in locating in an area close to its market is a bulk-gaining industry. This category includes businesses that produce goods that become heavier or more expensive to transport after the manufacturing process. A clear example of a bulk-gaining industry is a dry cleaner.
Dry cleaners offer a service that requires proximity to customers due to the need for frequent customer interaction and the provision of quick and local services. On the other hand, automobile manufacturers may not need to locate as close to markets due to their global distribution networks, and although shipbuilding companies and pharmaceutical companies need to consider proximity to certain resources or markets, they are not as tightly bound to immediate market locations as bulk gaining industries like dry cleaners.
