Final answer:
An indirect marketing channel includes intermediaries such as wholesalers, retailers, and agents. The correct answer is a direct marketing channel.
Step-by-step explanation:
An indirect marketing channel includes intermediaries such as wholesalers, retailers, and agents who help in distributing products to the final consumers. Direct marketing channels, on the other hand, involve the manufacturer or producer directly selling their products to consumers without intermediaries. Therefore, the correct answer is a direct marketing channel since the question asks for the option that is NOT included in an indirect marketing channel.
