Answer:
d. Ginger cannot be sued under the theory of product liability.
Step-by-step explanation:
Ginger sells goods to restaurant, and not to direct customers.
Customers can sue the restaurant owner for selling such baked products to them, and not to the direct manufacturer of such products.
Therefore, Ginger cannot be sued.
Although for any loss, the restaurant owner can sue Ginger, but not the direct customers under any scheme of Product liability. As the liability is of restaurant towards people consuming such baked products.
