Which is not transgenic plant?

Options

A. Soyabean
B. Maize
C. Golden rice
D. Cucumber

Answer

To determine which plant is not a transgenic plant, we need to analyze each option provided in the question.

### Step-by-Step Solution:

1. **Understanding Transgenic Plants**:
- Transgenic plants are those that have been genetically modified through the introduction of foreign DNA using biotechnology techniques. This process is known as genetic engineering.

2. **Analyzing Each Option**:
- **Option 1: Soybean**
- Soybean has been genetically modified to improve traits such as herbicide resistance and pest resistance. Therefore, soybean is a transgenic plant.

- **Option 2: Maize**
- Maize (corn) has also been genetically modified to enhance traits like pest resistance and herbicide tolerance. Thus, maize is a transgenic plant.

- **Option 3: Golden Rice**
- Golden rice is a genetically modified variety that has been engineered to produce beta-carotene, a precursor of vitamin A. Hence, golden rice is a transgenic plant.

- **Option 4: Cucumber**
- Cucumber, in its common varieties, has not been genetically modified and is considered a natural plant. Therefore, cucumber is not a transgenic plant.

3. **Conclusion**:
- Based on the analysis, the plant that is not transgenic is **cucumber**.

### Final Answer:
The plant that is not transgenic is **cucumber**.
