Which statement best defines competitive advantage?

• A. It occurs when a firm reduces R&D spending
• B. Implements a strategy that creates superior value for customers AND that its competitors are unable to duplicate
• C. It happens when a firm increases marketing budget
• D. It happens when a firm decreases product quality

Answer: (B)

Competitive advantage shows up when a firm delivers value to customers that is better than what rivals can offer and, crucially, that rivals cannot easily copy. The statement that describes creating superior value for customers and making it hard for competitors to duplicate captures both the performance edge and its sustainability, which is what distinguishes a true competitive advantage from short‑term gains. Merely cutting R&D may hurt future differentiation, and increasing marketing alone can boost visibility without ensuring the value competitors can’t imitate. Reducing product quality lowers value and damages competitiveness. When a company combines unique value for customers with barriers to imitation, it’s best suited to sustain advantage over time.
