Final answer:
Frozen food is least suited to sell online due to required refrigeration, risk of spoilage, and higher shipping costs.
Step-by-step explanation:
Out of the products listed, frozen food is probably the least suited to sell via the Internet. Selling frozen food online poses significant logistical challenges. The product has to remain frozen during transit, which requires specialized packaging and refrigeration. Additionally, the risk of food spoilage is higher, and shipping costs are likely to be higher due to the need for fast delivery times to ensure product quality. In contrast, products like DVD movies, game consoles, and books are more durable and have a longer shelf life, making them better suited for online sales and shipping.
