Which of the following best describes a supply chain?

• A. A company provides materials to another company to manufacture a product
• B. The process of distributing products to customers
• C. A network of websites sharing content
• D. A single company producing finished goods

Answer: (A)

A supply chain is about the network of organizations and activities that move a product from raw materials to the end customer, involving sourcing, manufacturing, logistics, and distribution across multiple firms. The option describing a company providing materials to another company to manufacture a product best matches this inter-organizational flow of inputs that spans several entities, which is the essence of a supply chain.

The other choices describe parts of the process or unrelated concepts: distributing products to customers focuses on logistics within the chain but doesn’t capture the multi-firm material flow; a network of websites sharing content isn’t about physical goods or supplier relationships; and a single company producing finished goods represents internal operations rather than the collaborative network that defines a supply chain.
