The ovary is half inferior in flowers of

Options

A. cucumber
B. cotton
C. guava
D. peach

Explanation

To determine which plant has a half inferior ovary, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Ovary Positioning**:
- The ovary in flowering plants can be classified based on its position relative to other floral parts (sepals, petals, and stamens). The three main types are:
- **Hypogynous**: Superior ovary (above other parts).
- **Perigynous**: Half inferior ovary (at the same level as other parts).
- **Epigynous**: Inferior ovary (below other parts).

2. **Identifying Half Inferior Ovary**:
- A half inferior ovary (perigynous) is characterized by the thalamus (flower base) growing around the ovary, forming a cup-shaped structure. This allows the ovary to be positioned at the same level as the other floral organs.

3. **Analyzing the Options**:
- The question provides four options:
- Cucumber
- Cotton
- Guava
- Peach

4. **Evaluating Each Option**:
- **Cucumber**: Exhibits an epigynous ovary (inferior).
- **Cotton**: Also has an epigynous ovary (inferior).
- **Guava**: Displays an epigynous ovary (inferior).
- **Peach**: Has a half inferior ovary (perigynous).

5. **Conclusion**:
- Based on the analysis, the plant with a half inferior ovary is **Peach**. Therefore, the correct answer is option number 4.

### Final Answer:
**Peach (Option 4)** has a half inferior ovary.
