Option 4 is the correct answer, supply chain developed from the physical distribution concept, inventory management and production efficiency

Explanation:

Supply chain involves the flow of goods and materials in and out of an organization with emphasis on effective and efficient distribution network, inventory management and production.

There are two major sides to supply chain, the inbound and outbound logistics. The inbound refers to movement of goods and services into the organization while outbound has to do with movement outwards of finished products.

For steady availability of finished products in the market place both sides must be well planned.
