Answer:
B) related and supporting industries
Explanation:
Related and supporting industries refer to the whole dimension of an industry within an economy.
We can use a much more domestic example for this, Miami and vacation industry. The vacation industry is not just the hospitality industry (hotels, etc.), it includes a lot more: resort developers, shopping centers, homeowners' associations, community colleges and universities, retail associations, etc. When an industry is so dominant on a certain location, several supporting industries are needed. For example, chefs need to be trained somewhere, cars have to be rented, retail stores must get organized (e.g. Espanola Way and Lincoln Road in Miami Beach), pool cleaning companies are needed, etc. The vacation industry employs hundreds of thousands of people in southern Florida.
