French fries made from stored potatoes would have changes in:

French fries made from stored potatoes would exhibit changes in texture, flavor, and color, which corresponds to the parameters described as I, II, and III.

When potatoes are stored over time, they undergo various biochemical changes. The texture of the potatoes can degrade due to moisture loss and enzymatic activities, making them less crisp when cooked. Flavor changes may occur due to the conversion of starches to sugars during storage, leading to a sweeter taste that can significantly affect the final product's palatability. Additionally, color changes can occur, particularly if potatoes develop greening or sprouting, which is usually caused by exposure to light and signifies a higher solanine content.

The combination of these changes illustrates why all three listed factors are relevant when considering the quality of French fries made from stored potatoes, affirming that the correct response includes all aspects.
