Answer

To determine which of the following plants has a superior ovary, we need to understand the concept of ovary position in flowers.

### Step-by-Step Solution:

1. **Understand the Terms**: The ovary is part of the female reproductive structure of a flower, known as the gynoecium. The position of the ovary can be classified into three types: superior, inferior, and half-inferior.

2. **Define Superior Ovary**: A superior ovary (also known as hypogynous) is one where the ovary is positioned above the other floral parts (such as petals, sepals, and stamens). In this case, the other floral parts are attached below the ovary.

3. **Identify the Options**: The plants given in the question are:
- Peach
- Guava
- China Rose
- Rose

4. **Analyze Each Option**:
- **Peach**: It has a semi-inferior ovary.
- **Guava**: It has an inferior ovary.
- **China Rose**: It has a superior ovary.
- **Rose**: It has a superior ovary.

5. **Conclusion**: Among the options, both China Rose and Rose have a superior ovary. However, since the question asks for one plant, we can select **China Rose** as the answer.

### Final Answer:
**China Rose** has a superior ovary.
