Option 1 -> Manufacturer, Retailer and Consumer - This represents a one-level channel as it has only one intermediary (Retailer) between manufacturer and consumer.
Option 2 -> Manufacturer, Wholesaler and Retailer - This represents a two-level channel with two intermediaries (Wholesaler and Retailer) between manufacturer and consumer.
Option 3 -> Agent, Wholesaler and Retailer - This lists three intermediaries that operate between the manufacturer and consumer, forming a three-level distribution channel.
Option 4 -> Wholesaler, Retailer and Consumer - This represents a two-level channel as Consumer is the end-point, not an intermediary, leaving only two intermediaries (Wholesaler and Retailer).
Hence, Option 3: Agent, Wholesaler and Retailer -> A three-level channel of distribution is defined by the number of intermediaries between the manufacturer and the final consumer.
