Answer: C. Focused Cost Leadership
Step-by-step explanation:
Focused cost leadership happens when a company tries to focus on one part of the market such that it is able to take advantages of the unique opportunities offered there to offer the lowest prices to that specific part of the market.
Sun County Airlines is focusing on leisure destinations and yet offering it at low cost. It is therefore trying to focus specifically on that market whilst offering the lowest price which makes this a focused cost leadership strategy.
