Final answer:
Zane's understanding that many competitors fail because they focus on selling instead of prioritizing customer service highlights the importance of customer service in business success. The correct option is A.
Step-by-step explanation:
Zane's understanding that many of his competitors fail because they think they're in the 'selling stuff' business and not the 'customer service' business demonstrates that Zane recognizes the importance of customer service in the success of a business. Customer service is more important than selling products. When a business prioritizes providing excellent customer service, it can build a strong reputation, gain customer loyalty, and ultimately drive sales.
By focusing on customer service, businesses can differentiate themselves from their competitors and create a positive customer experience. In today's highly competitive market, businesses need to go beyond simply selling products to create customer satisfaction and build long-term relationships.
For example, if one business sells a variety of products but lacks good customer service, customers may have negative experiences and choose not to return. On the other hand, a business that offers excellent customer service even with a limited range of products may attract and retain loyal customers.
