Final answer:
TDZ Manufacturing should use traveling sales representatives to change its distribution system from an indirect channel to a direct channel system. Option C.
Step-by-step explanation:
The company should use traveling sales representatives to achieve the change in distribution system from an indirect channel to a direct channel system. Traveling sales representatives directly visit potential customers to promote and sell products on behalf of the company.
They can establish direct relationships with customers, gather feedback, and ensure efficient distribution of products.
This approach eliminates the need for intermediaries like cash-and-carry wholesalers, dealers, full-function wholesalers, and retailers. The company can take control of its distribution process, reduce costs, and have a better understanding of customer needs. Option C.
