Correct Answer: Option D
Explanation
Green tea (Camellia sinensis, family Theaceae) is the richest known dietary source of flavan-3-ols (catechins), including: EGCG (epigallocatechin-3-gallate) — most abundant (~50–75% of catechins); EGC (epigallocatechin); ECG (epicatechin gallate, ~15%); EC (epicatechin). Epicatechin gallate (ECG) is specifically a gallic acid ester of epicatechin. Total catechins in green tea can reach 30% of dry weight. These polyphenolic antioxidants are associated with cardiovascular, metabolic, and neuroprotective benefits. Berries contain anthocyanins; carrots contain carotenoids (-carotene); oranges contain flavanones (hesperidin, naringenin) and vitamin C.
