Answer 1

Key Points

Golden rice is a transgenic rice variety.
Transgenic plants are obtained through genetic engineering that uses recombinant DNA technology.
Transgenic plants are generated by introducing foreign DNA into a cell and regenerating a plant from that cell.

Explanation:

Golden rice is rich in vitamin A.
It is a genetically modified variety of rice (Oryza sativa).
It contains good quantities of β-carotene, the precursor of vitamin A.
The rice grains are yellow in colour due to presence of β-carotene, thus it is commonly called golden rice.
This strain of rice is developed to deal with the vitamin A deficiency in nutrient deficient population.
It is one of the successfully biofortified food.

Hence, the correct option is (1) vitamin A.

Additional Information

Genetically modified plants contain high nutritional value of food.
Genetic modification has made crops more tolerant to the abiotic stress, and helped to post harvest losses.
Reduced reliance on chemical pesticides and increased efficiency of mineral usage by plants.
Example- Flavr savr tomatoes, Bt cotton, etc.
