Option 1 -> Feedback is a marketing communication tool, not a physical distribution component.

Option 2 -> Includes all core components: order-processing (receiving and handling orders), inventory control (managing stock levels), warehousing (storing goods), and transportation (moving goods to customers).

Option 3 -> Promoting is a marketing activity focused on communication and persuasion, not physical distribution of goods.
