Solution

The correct option is D Golden rice
Night blindness is the inability to see normally in subdued light. It is usually a result of vitamin A deficiency. Golden rice is such a biofortified crop. Golden rice grains are easily recognisable by their yellow to orange colour. The stronger the colour the more carotene. Rice produces provitamin A (carotene) in the leaves but not in the grain, where the biosynthetic pathway is turned off during plant development. In golden rice, two genes have been inserted into the rice genome by genetic engineering, to restart the carotenoid biosynthetic pathway leading to the production and accumulation of carotene in the grains. Both genes are naturally involved in carotene biosynthesis.
Therefore, the correct answer is option D.
