Answer: B. Indirect channel
Explanation: The channel of distribution is defined as a network of organizations that connect the producer/manufacturer of goods and services with the end-users or consumers of those goods or services. By employing the services of wholesalers and retailers, the shoe manufacturer is using the indirect channel of distribution, specifically the two-level channel (Manufacturer to Wholesaler to Retailer to Customer). Also known as selling to intermediaries, it involves wholesalers buying the bulk of goods from the manufacturers, then selling to retailers (after breaking them down into small packages) who eventually sell it to the end customers.
