The problem of blindness in poor countries can be taken care of by using which of the following?

Options

A. Golden rice
B. Transgenic tomato
C. Transgenic maize
D. Bt brinjal

Answer

**Step-by-Step Solution:**

1. **Identify the Problem**: The question asks about addressing the problem of blindness in poor countries. The primary cause of blindness in these regions is often related to nutritional deficiencies, particularly vitamin A deficiency.

2. **Understand the Role of Vitamin A**: Vitamin A is crucial for vision. It is a precursor for the formation of visual pigments in the retina, specifically rhodopsin in rods and iodopsin in cones. A deficiency in vitamin A can lead to conditions like night blindness and xerophthalmia.

3. **Evaluate the Options**: The question provides several options to consider:
- Golden rice
- Transgenic tomato
- Transgenic maize
- Bt brinjal

4. **Analyze Each Option**:
- **Golden Rice**: This is genetically modified rice that is enriched with beta-carotene, which the body can convert into vitamin A. This makes it a viable solution for addressing vitamin A deficiency and, consequently, blindness.
- **Transgenic Tomato**: While it may have benefits, it is not specifically designed to address vitamin A deficiency.
- **Transgenic Maize**: Similar to the tomato, it does not directly address the issue of vitamin A deficiency.
- **Bt Brinjal**: This is a pest-resistant variety of brinjal and does not have any relation to vitamin A content.

5. **Conclusion**: Based on the analysis, the best option to address the problem of blindness due to vitamin A deficiency in poor countries is **Golden Rice**.

**Final Answer**: Golden Rice (Option 1) is the right option for addressing blindness in poor countries.
