Final answer:
The correct answer to the provided question is Delaware North, which is a prominent foodservice contractor in airports internationally, distinguishing it from franchises such as McDonald's and Subway. Option C is correct.
Step-by-step explanation:
The popular airport foodservice contractors include Sodexo, ARAMARK, and Delaware North. While options such as McDonald's and Subway are common food outlets found in airports, they are not typically classified as foodservice contractors but rather individual franchises or quick-service restaurants.
Delaware North is known for providing food, beverage, and retail services in airports, sports stadiums, and entertainment complexes globally. Starbucks, like McDonald's and Subway, operates many airport locations, but it is not considered a typical foodservice contractor in the same sense as Delaware North.
