How to think about questions like this

Application questions test whether you can connect a real-world example to the right framework. The trick is to ignore the surface details (industry, company name) and focus on the underlying mechanic the example illustrates.

For Cost Leadership Strategy specifically, look for the signal: Low cost lets you set price below rivals and still profit, or match price and earn margin. That signal is what distinguishes the right answer from plausible-sounding alternatives.
