'Golden rice' variety of rice shows:

enhanced nutritional value of food

The correct answer is Option (1)- enhanced nutritional value of food

Golden rice is a transgenic variety of rice (Oryza Sativa) which contains good quantities of β-carotene ( provitamin A- inactive state of vitamin A). β-carotene is a principle source of vitamin A. Since the grains (seeds) of the rice are yellow in colour due to β-carotene, the rice is commonly called golden rice.

Golden Rice is engineered to produce beta-carotene, a precursor to vitamin A. This enhancement addresses vitamin A deficiency, which is a significant health issue in many parts of the world. Consuming Golden Rice can help improve the nutritional status of individuals who rely on rice as a staple food, thereby reducing the risk of vitamin A deficiency-related diseases, such as blindness and immune deficiencies.
