Agents or firms that act as a middle person in the chain of distribution between the producer and consumers of a product; examples include retailers, distributors, and agents.

• A. Direct marketing
• B. Distributors
• C. Retailers
• D. Intermediaries

Answer: (D)

In distribution channels, the term for firms that sit between producers and customers is intermediaries. They move products along the chain and help reach different markets. Direct marketing describes selling straight to consumers with no middlemen, so it doesn’t capture the middleman role. Retailers and distributors are concrete examples of intermediaries, and agents also fulfill this middleman function. Because the question asks for the general label that covers all such middlemen, the best answer is intermediaries.
