The correct option is A golden rice
Golden rice is a vitamin A rich variety of rice developed by rDNA technology and used in the treatment of vitamin A deficiency. In this specific case, the rice plant was genetically modified to accumulate provitamin A (β-carotene) in the grain, something that doesn't happen in naturally occurring rice plants.
Vitamin A deficiency (VAD) is considered to be one of the most harmful forms of malnutrition in the developing world. It can cause blindness, limit growth, and weaken the body's immune system, thereby increasing morbidity and mortality. The advantage of golden rice is that it can be used in areas where Vitamin A deficiency is common and so can help prevent blindness.
