Which of the following are key components of a supply chain?

The selection of suppliers, manufacturers, distributors, retailers, and customers as key components of a supply chain highlights the interconnected nature of the entire supply chain network. Each element plays a vital role in the overall process of delivering a product from raw materials to end customers.

Suppliers provide the necessary raw materials or components that manufacturers use to create finished products. Manufacturers then produce these goods, which may be sent to distributors who handle storage and transportation. Retailers exhibit and sell these finished products to customers, who ultimately consume the goods.

This comprehensive view captures the full spectrum of the supply chain, emphasizing that it is not solely dependent on any individual component but rather the synergy between all members. Each of these components has a specific function that facilitates the movement of goods and services through various stages, showcasing the complexity and collaborative effort required in supply chain management.

The other options either omit critical elements of the supply chain or focus too narrowly, neglecting the integration needed for effective supply chain operations. For example, only considering suppliers and manufacturers excludes essential links like distribution and retail, which are necessary for delivering products to customers.
