What are some of Ryanair's major competitors in the low-cost airline market?

B is the correct answer because EasyJet and Wizz Air are both prominent players in the low-cost airline sector, much like Ryanair. These airlines focus on providing affordable flight options to travelers, catering to a similar demographic and often operating in overlapping markets across Europe. They employ comparable business models that emphasize cost-cutting strategies, no-frills service, and ancillary revenue from additional services.

In contrast, the other options feature airlines that either operate on a different business model or target a more premium market segment. American Airlines and Delta Airlines, for instance, are major legacy carriers that provide full-service flights with additional comforts and services, making them less direct competitors to Ryanair’s low-cost structure. British Airways and Lufthansa similarly fall into the full-service category, offering international flights with extensive service options, while Spirit Airlines and Frontier Airlines operate in the low-cost space but are primarily focused on the North American market rather than competing directly with Ryanair in Europe.
