Concept:
Channel levels refer to the number of intermediaries involved between the producer and the consumer in the distribution process.
Answer:
The channel Producer → Retailer → Consumer is known as a one-level channel of distribution.
In this channel, there is only one intermediary, i.e., the retailer, who purchases goods directly from the producer and sells them to the final consumer.
This type of channel is commonly used for consumer goods where quick delivery and direct retailer involvement are important.
