B. Gives high yield and is rich in vitamin A
C. Is completely resistant to all insect pests and diseases of paddy
D. Given high yield but has no characterstic aroma

Answer

**Step-by-Step Solution:**

1. **Identify the Transgenic Rice**: The question asks about an improved variety of transgenic basmati rice. The well-known transgenic rice variety is called "Golden Rice."

2. **Understand the Characteristics of Golden Rice**: Golden Rice is genetically modified to contain a gene that enables it to produce beta-carotene, which is a precursor to vitamin A. This is one of its primary benefits.

3. **Evaluate the Options**: The question provides four options regarding the characteristics of this transgenic rice. We need to analyze each option:
- **Option 1**: Does not require chemical fertilizers and growth hormones. (Not specifically true for Golden Rice)
- **Option 2**: Gives high yields and is rich in vitamin A. (True, as it is designed to be high yielding and contains beta-carotene)
- **Option 3**: Is completely resistant to all insects, pests, and diseases of paddy. (Not accurate, as no crop is completely resistant to all threats)
- **Option 4**: Gives high yield but has no characteristic aroma. (Partially true, but the key point is the richness in vitamin A)

4. **Select the Best Option**: Based on the analysis, the most appropriate option is **Option 2**, which states that the improved variety of transgenic basmati rice gives high yields and is rich in vitamin A.

5. **Conclusion**: Therefore, the correct answer to the question is that the improved variety of transgenic basmati rice is one that gives high yields and is rich in vitamin A.
