The correct option is A
True. A caryopsis is a type of simple dry fruit—one that is monocarpellate (formed from a single ovary) and indehiscent (not opening at maturity) and the pericarp (outer layer of fruit) is fused with the thin seed coat. Maize grain has all the above-mentioned features and hence is a fruit called caryopsis which is typical of grasses and cereals.
