Answer : a
Hints & Solutions
(a) Golden rice is a form of rice with biosynthesis of beta-carotene (a form of vitamin A) which gives its golden or yellow colouring. It is considered a type of genetically modified rice (GMO) and a fortified food that is produced to combat a vitamin A deficiency in areas where this vitamin is scarce. It was in the late 1990s that two European scientists developed Golden Rice after inserting beta carotene-enriched rice gene from daffodil to rice.
