Vitamin A
The correct answer is Option 2: Vitamin A.
What is Golden Rice?
Golden Rice is a variety of rice (Oryza sativa) produced through genetic engineering. It was specifically developed to combat Vitamin A Deficiency (VAD) in developing countries, where rice is a staple food but lacks essential micronutrients.
How it Works
Scientists modified the rice by inserting genes from a daffodil plant (Narcissus pseudonarcissus) and a soil bacterium (Erwinia amylovora).
These inserted genes complete a metabolic pathway that allows the edible part of the rice (the endosperm) to synthesize beta-carotene (\(\beta\text{-carotene}\)).
Beta-carotene is a provitamin, which means that once a human eats it, our body naturally converts it into Vitamin A.
It is the presence of beta-carotene that gives the modified rice grains their distinctive, vibrant golden-yellow color.
