Final answer:
Zappos provides value to its customers by c) offering the best selection of shoes and the best service to online shoppers (Option C).
Step-by-step explanation:
Zappos values providing a wide selection of shoes and excellent service, reflecting a preference for variety over efficiency in their business model, balancing consumer preferences for diverse stylistic and functional needs. This focus on variety as opposed to efficiency plays into the larger discussion of the opportunity cost of variety in products. While production efficiency, like the model used by Amazon, can reduce costs, it may not satisfy all consumer needs - which may include a diverse selection tailored to a myriad of occasions, styles, and functions.
The historical shift in shoe production from individual craftsmanship to the putting-out system, where tasks were divided among different groups to standardize parts like shoe soles and uppers, demonstrates a movement towards efficiency. However, this may have reduced the variety of shoes available, while modern retailers like Zappos have brought back a focus on variety by providing a vast selection alongside excellent customer service. Firms today, including large ones like Amazon and small local businesses, must balance the trade-offs between efficiency and variety, considering their cost structures and what they choose to offer in terms of products, services, and pricing.
When it comes to footwear, considerations such as comfort, fit, and suitability to the occasion are paramount. Products like high heels, which may be stylish, aren't always practical or comfortable for prolonged wear. This illustrates the complexity of balancing consumer preferences when discussing the right amount of variety in a market.
Thus, the correct option is C.
