An improved variety of transgenic basmati rice

Options

A. Does not require chemical fertilisers and growth hormones
B. Gives high yield and is rich in vitamin A
C. Is completely resistant to all insect pests and diseases of paddy
D. Gives high yield but has no characteristic aroma

Answer

**Step-by-Step Solution:**

1. **Understanding Transgenic Basmati Rice**: Transgenic basmati rice refers to rice that has been genetically modified to enhance certain traits. In this case, the focus is on an improved variety that has been developed through biotechnology.

2. **Identifying Key Features**: The improved variety of transgenic basmati rice is designed to have specific advantages over traditional varieties. These advantages may include higher yield, enhanced nutritional value, and resistance to certain pests and diseases.

3. **Nutritional Enhancement**: One of the significant improvements in this transgenic rice is the incorporation of 3-beta carotene biosynthetic genes. These genes help in the production of beta carotene, which is a precursor to vitamin A. This enhancement is crucial for addressing vitamin A deficiency in populations that rely heavily on rice as a staple food.

4. **Golden Rice**: The transgenic basmati rice that contains these genes is often referred to as "Golden Rice" due to its golden color, which is a result of the beta carotene content. This rice not only provides higher yields but also contributes to better nutrition.

5. **Evaluating Options**: The question provides several options regarding the characteristics of the improved variety of transgenic basmati rice.
- It does not require chemical fertilizers and growth hormones.
- It gives high yield and is rich in vitamin A.
- It is completely resistant to all insect pests and diseases of paddy.
- It gives high yield but no characteristic aroma.

6. **Choosing the Correct Answer**: Upon evaluating these options, the correct answer is that the improved variety of transgenic basmati rice gives high yield and is rich in vitamin A. The other options are incorrect as they either exaggerate the benefits or misrepresent the characteristics of the rice.

**Final Answer**: The improved variety of transgenic basmati rice gives high yield and is rich in vitamin A.
