A transgenic food crop which may help in solving the problem of night blindness in developing countries is

Options

A. Bt soybean
B. Golden rice
C. starlink maize
D. flavr savr tomatoes

Answer

**Step-by-Step Solution:**

1. **Understanding Night Blindness**: Night blindness is a condition where an individual has difficulty seeing in low light or darkness. This condition is often caused by a deficiency in vitamin A.

2. **Identifying the Cause**: Vitamin A is essential for maintaining healthy vision, and its deficiency can lead to various eye problems, including night blindness.

3. **Linking Food Crops to Vitamin A**: In many developing countries, rice is a staple food. Therefore, enhancing rice to contain higher levels of vitamin A can help address the deficiency in the population.

4. **Introduction of Genetic Engineering**: Scientists have utilized biotechnology to genetically engineer rice to produce beta-carotene, which is a precursor to vitamin A.

5. **Naming the Transgenic Crop**: The genetically modified rice that contains beta-carotene is known as "Golden Rice." It is called "golden" due to the yellow color of the rice grains, which is a result of the beta-carotene content.

6. **Conclusion**: Therefore, the transgenic food crop that may help in solving the problem of night blindness in developing countries is **Golden Rice**.

**Final Answer**: Golden Rice
