Ford Has Produced a High-Value Version of Its Ford Expedition

Ford has produced a high-value version of its Ford Expedition SUV. Sold as the Lincoln Navigator and priced around $10,000 higher, the Navigator has the same body, engine, chassis, and design as the Expedition, but through skilled advertising and marketing, supported by some fairly minor features changes (e.g., more accessories and the addition of a Lincoln-style engine grille and nameplate) , Ford has fostered the perception that the Navigator is a "luxury SUV." This demonstrates how the marketing function can:

A) help a firm reduce cost of production across product lines.
B) create value by giving valuable inputs to the research and development function.
C) increase the value that consumers perceive to be contained in a firm's product.
D) create value by performing its activities efficiently so lower costs result.
