B. Rose has inferior ovary while china rose has superior ovary
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 determine the correct 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. Here’s a step-by-step breakdown of the solution:

### Step-by-Step Solution:

1. **Identify the Types of Ovaries**:
- There are three main types of ovary positions in flowering plants:
- **Hypogynous**: Superior ovary (ovary above other floral parts).
- **Perigynous**: Semi-inferior ovary (ovary at the same level as other floral parts).
- **Epigynous**: Inferior ovary (ovary below other floral parts).

2. **Classify the Rose**:
- The rose is classified as **perigynous**, meaning it has a semi-inferior ovary. In this type, the gynoecium is at the center, and other floral parts (like petals and sepals) are at the same level.

3. **Classify the China Rose**:
- The China rose, on the other hand, is classified as **hypogynous**, which means it has a superior ovary. In this case, the ovary is positioned above the other floral parts.

4. **Determine the Correct Option**:
- Based on the classifications:
- Rose has a semi-inferior ovary (perigynous).
- China rose has a superior ovary (hypogynous).
- Therefore, the correct option that describes this difference is **D**: "Rose has semi-inferior ovary while China rose has superior ovary."

### Final Answer:
The correct difference between the ovary of rose and China rose is that **rose has a semi-inferior ovary while China rose has a superior ovary** (Option D).
