Which of the following is NOT typically part of a retailer's function?

The correct answer is C, as manufacturing goods falls outside the typical functions of a retailer. Retailers primarily engage in purchasing products from manufacturers or wholesalers and then reselling those goods directly to consumers. Their role focuses on providing a sales platform and enhancing the buying experience for customers, rather than producing the products themselves.

Retailers also manage customer relationships, ensuring satisfaction and loyalty through effective service and engagement strategies. Purchasing goods is an essential function, as it allows retailers to stock their inventory and meet consumer demand. Thus, manufacturing is not a typical retailer function, making this the right choice.
