Final answer:
Achieving a competitive advantage results in the ability to consistently offer high-value goods or services that are difficult for competitors to replicate, thus allowing a firm to command above-normal profits.
Step-by-step explanation:
The key result of achieving a competitive advantage is B. An ability to consistently do something of high value which one's competitors cannot replicate quickly or do as well. Firms strive for a competitive edge to earn higher profits by producing products more cheaply or creating products with characteristics consumers want. A competitive advantage does not inherently entail avoiding government regulations, driving competitors out of business, establishing a monopolistic position, or dictating consumer needs and preferences, as these strategies can have ethical, legal, and practical implications that may not align with sustaining a long-term competitive advantage. Instead, earning above-normal profits typically stems from innovation, effective cost management, and the distinction of goods and services that appeal to consumers and are not easily duplicated by others.
