Which of the following activities is not considered a function of physical distribution?

In the context of physical distribution, transportation, warehousing, and distribution inventory are all critical components that facilitate the movement of goods from the manufacturer to the end customer.

Transportation involves the physical movement of products from one location to another, which is a core aspect of physical distribution. Warehousing refers to the storage of goods to ensure that inventory is available when needed, thus playing a vital role in maintaining the flow of products. Distribution inventory focuses on managing stock levels that are necessary for timely delivery to customers.

Production control, however, is primarily concerned with the management of manufacturing processes and ensuring that production meets demand efficiently. It deals with planning, scheduling, and controlling the processes that transform raw materials into finished goods rather than managing the physical movement and storage of products. Therefore, it is not classified as a function of physical distribution, making it the correct answer in this context.
