Which statement best describes the nature of a sustained competitive advantage?

• A. It lasts only until competitors imitate.
• B. It relies on unique resources/capabilities that are hard to imitate.
• C. It is solely based on price discounts.
• D. It cannot be sustained in any market.

Answer: (B)

The main idea here is that a sustained competitive advantage comes from resources and capabilities that rivals find hard to copy, allowing a firm to outperform competitors over time. The best statement captures this by saying the advantage relies on unique resources and capabilities that are hard to imitate. When a company possesses valuable, rare, and difficult-to-copy assets or routines—such as a strong brand, complex know-how, innovative technology, or well-integrated business systems—it creates barriers to imitation that help maintain superior performance even as competitors try to replicate it.

Why the other options don’t fit: lasting only until imitation would imply the advantage isn’t truly enduring, which contradicts the idea of a sustained edge. Relying solely on price discounts describes a vulnerability to competitive price matching and isn’t a durable differentiator. Saying it cannot be sustained in any market ignores real-world cases where firms maintain advantages for extended periods due to hard-to-imitate resources or capabilities.
