Plant-based foods contain which antioxidant enzyme according to the material?

Explanation:
Antioxidant enzymes in plant foods include glutathione peroxidases, which help neutralize harmful peroxides. These enzymes catalyze the reduction of hydrogen peroxide and lipid peroxides to water and alcohols, using glutathione as a substrate. This action protects cells from oxidative damage and supports the antioxidant capacity of plant-based foods. While plants can contain other antioxidant enzymes, the material specifically identifies glutathione peroxidases in plant-based foods, which is why this option is the best choice.
