What is a supply chain?

• A. A network of stores selling products
• B. A system of activities, people, information, organizations, and resources participating in moving a service or product from supplier to customer
• C. A marketing department's workflow
• D. A single company’s internal logistics only

Answer: (B)

The main idea is that a supply chain is the system of activities, people, information, organizations, and resources involved in moving a product or service from its origin with a supplier to the end customer. This definition highlights end-to-end coordination across multiple entities—upstream suppliers, manufacturers, distributors, retailers, and customers—plus the information that ties them together, like orders, forecasts, and shipment data. It shows why supply chains are about more than just where you buy things or your company’s internal steps; they are about the whole flow that delivers value to the customer. The other options are narrower: a network of stores focuses only on retail points; a marketing department's workflow covers internal marketing tasks; and internal logistics alone ignores external partners and the full journey from supplier to customer.
