Which of the 'following is true for Golden rice' ?

Options

A. It is Vitamin A enriched, with a gene from daffodil
B. It is pest resistant, With a gene from Bacillus thuringiensis.
C. It is drought tolerant, developed using Agrobacterium vector.
D. It has yelloe grains, because of a gene introduced from a primitive variety of rice

Answer

**Step-by-Step Solution:**

1. **Understanding Golden Rice**: Golden rice is a genetically modified variety of rice that has been engineered to produce beta-carotene, a precursor to vitamin A. This modification aims to combat vitamin A deficiency, which is a significant health issue in many parts of the world.

2. **Analyzing the Options**:
- **Option 1**: "It is a vitamin A enriched with a gene from daffodil."
- This option is partially correct. Golden rice is enriched with beta-carotene, which is a precursor to vitamin A, and it does contain genes from daffodil.
- **Option 2**: "It is pest resistant with a gene from Bacillus thuringiensis."
- This is incorrect. Golden rice is not primarily developed for pest resistance; that trait is associated with other genetically modified crops.
- **Option 3**: "It is broad resistant developed using agrobacterium vector."
- This is also incorrect. While Agrobacterium is a common method for gene transfer in plants, golden rice is specifically engineered for beta-carotene production, not broad resistance.
- **Option 4**: "It has yellow grains because of a gene introduced from a primitive variety of rice."
- This is misleading. The yellow color of golden rice is due to the presence of beta-carotene, not from a primitive variety of rice.

3. **Conclusion**: After analyzing all the options, the first option is the only true statement about golden rice. It is indeed a vitamin A enriched rice variety that incorporates genes from daffodil to produce beta-carotene.

**Final Answer**: The correct statement about golden rice is: "It is a vitamin A enriched with a gene from daffodil."
