Phytochemicals are also known as Phytonutrients which are found in plant-based food such as vegetables, fruits, cereals, and legumes. They help the body to improve functioning and reduce the risk of certain kinds of diseases. They are additional chemical substances for the body to be healthy.

1. The phytochemicals have antioxidant properties and they are protective against cardiovascular diseases and cancers. They help in preventing age-related macular degeneration (AMD) and cataracts. Option C is incorrect as the Phytochemicals are not found to activate cancer instead, they reduce the risk of cancer formation.

The answer is c. inhibit the activity of enzymes to activate carcinogens.

2. Flavonoids are categorized under antioxidant polyphenol, responsible for reducing the risk of cardiovascular diseases. They are found to improve and maintain vascular endothelial functioning. Tannins prevent inflammation, diarrhea and act as a diuretic. Curcumin and tannins are found to have anti-cancer properties. Ellagic acid has antioxidant, anti-inflammatory, anti-microbial, cardioprotective properties. Sulfides have antitumor activities, detoxes liver enzymes lower cholesterol. Limonene detoxifies the liver. Saponins are anticancerous and lowering blood cholesterol.
