Answer:
Sustainable Competitive Advantage.
Explanation:
A sustainable competitive advantage is something - an ability, an asset, an attribute - that is difficult for other companies to duplicate. That gives, of course, superiority to the company that detains this advantage over its competitors. A real-life example would be Coca-Cola's brand. It is a powerful brand that was built and consolidated over several decades. Having a powerful brand means customers prefer it over other brands.
