C. Rose has semi- inferior ovary while china rose has inferior ovary
D. Rose has semi- inferior ovary while china rose has superior ovary

Answer

To solve the question regarding the difference between the ovary of rose and China rose, we need to understand the classification of ovaries based on their position in relation to other floral parts.

### Step-by-Step Solution:

1. **Understanding Ovary Position**:
- The ovary can be classified into three types based on its position:
- **Hypogynous**: The ovary is superior, meaning it is positioned above the other floral parts (sepals, petals, and stamens).
- **Perigynous**: The ovary is half-inferior, meaning it is positioned at the same level as the other floral parts.
- **Epigynous**: The ovary is inferior, meaning it is positioned below all other floral parts.

2. **Identifying the Ovary of China Rose**:
- China rose (Hibiscus rosa-sinensis) has a **hypogynous** ovary. This means that its ovary is superior to the other floral parts.

3. **Identifying the Ovary of Rose**:
- The rose (Rosa spp.) has a **perigynous** ovary. This means that its ovary is positioned at the same level as the other floral parts.

4. **Comparing the Two**:
- Therefore, the key difference is:
- **China Rose**: Hypogynous (superior ovary)
- **Rose**: Perigynous (semi-inferior ovary)

5. **Selecting the Correct Option**:
- Based on the definitions and examples provided, the correct statement is that the rose has a semi-inferior ovary while the China rose has a superior ovary.

### Final Answer:
The correct difference is that the rose has a perigynous ovary (semi-inferior) while the China rose has a hypogynous ovary (superior).
