C.

Golden rice

Golden rice is a variety of Oryza sativa (rice) produced through genetic engineering to biosynthesize Beta-acetone, a precursor of vitamin-A in the edible part of rice (i.e., endosperm). The research that led golden rice was conducted with the goal of helping children who suffer from vitamin-A deficiency. Because many children in countries where there is a dietary deficiency in vitamin-A rely on rice as a staple food, the genetic modification of rice to produce the vitamin-A precursor beta-carotene is seen as a simple and less expensive alternative to vitamin supplements.
