Which statement about sustainable competitive advantages is most accurate?

• A. It relies solely on aggressive advertising
• B. It is difficult to imitate and supported by unique resources
• C. It is easily replicable by competitors
• D. It is based on a temporary price discount

Answer: (D)

Sustainable competitive advantage comes from resources and capabilities that others cannot easily imitate, creating lasting value and a defensible position for the firm. When a company has unique, valuable, rare, and inimitable assets—such as protected technology, exclusive partnerships, strong brand equity, or superior routines and processes—it builds barriers that competitors cannot readily overcome. Those durable assets allow the company to perform well over time, not just in the short term.

A temporary price discount doesn’t fit this idea because price-based advantages are quickly matched by rivals and tend to vanish once the promotion ends. Advertising can help build a brand, but without underlying hard-to-copy resources or capabilities, it seldom yields a lasting edge. The key takeaway is that lasting advantage comes from hard-to-imitate resources and capabilities, not from short-lived tactics like temporary price cuts.
