Final answer:
Liquidation is not one of the most frequently used strategic approaches to building competitive advantage.
Step-by-step explanation:
The answer to the question is D. Liquidation.
The three most frequently used strategic approaches to building competitive advantage are Cost Leadership, Differentiation, and Focus. Cost Leadership involves achieving the lowest cost of production and distribution in order to offer products at a lower price than competitors. Differentiation focuses on creating unique and desirable products or services that are perceived as superior by customers. Focus involves targeting a specific segment of the market and tailoring products or services to meet their unique needs.
Liquidation, on the other hand, is not a strategic approach to building competitive advantage. It refers to the process of selling off a company's assets in order to pay off debts and close down the business.
