Which of the following is true for Golden rice?

A) It has yellow grains, because of a gene introduced from a primitive variety of rice

B) It is Vitamin A enriched, with a gene from daffodil

C) It is pest resistant, with a gene from Bacillus thuringiensis

D) It is drought tolerant, developed using Agrobacterium vector

Answer: B) It is Vitamin A enriched, with a gene from daffodil

Explanation: Golden rice is produced using recombinant DNA technology. It is highly enriched in vitamin A with a gene cloned from daffodil.

The main source of Vitamin A is beta-carotene. From the Daffodil plant, the genes involved in the synthesis of beta carotene can be obtained. This gene is introduced into the rice plant with the help of Agrobacterium tumefaciens vector.

Hence, from the above-mentioned options, “It is Vitamin A enriched, with a gene from daffodil” option is correct.
