Answer

To answer the question "Example of an incomplete flower is ………...", we need to understand what an incomplete flower is and identify examples of such flowers.

### Step-by-Step Solution:

1. **Define a Complete Flower**:
A complete flower has four main parts: petals, sepals, stamens, and pistils.

2. **Identify Incomplete Flowers**:
An incomplete flower is one that lacks one or more of these parts. For example, if a flower is missing either stamens or pistils, it is considered incomplete.

3. **Evaluate the Options**:
The options given are:
- Option A: B
- Option B: China rose
- Option C: Dead form
- Option D: Mustard

4. **Analyze Each Option**:
- **Option A (B)**: This does not provide a valid flower name.
- **Option B (China rose)**: This flower has all four parts (petals, sepals, stamens, pistils), so it is a complete flower.
- **Option C (Dead form)**: This does not appear to be a valid flower name.
- **Option D (Mustard)**: This flower also has all four parts, making it a complete flower.

5. **Conclusion**:
Since none of the options provided are valid examples of incomplete flowers, we conclude that there may be an error in the options listed. However, a common example of an incomplete flower is one that lacks stamens or pistils, such as a flower from the genus *Cucurbita* (like squash or pumpkin), which can be unisexual.

### Final Answer:
The question does not provide a correct option among the given choices. An example of an incomplete flower could be a flower from the *Cucurbita* genus.
