For quick-response manufacturing to work to the retailer’s advantage in the respect mentioned above, which of the following must be true

A．The cost per piece of manufacturing various articles in small batches exceeds the cost per piece of manufacturing large quantities of those articles.

B．The equipment necessary to provide the direct feedback is different from the equipment that supports conventional inventory control.

C．Consumers do not patronize a store that does not stock the model, pattern, or style that they prefer.
