B. Opposite phyllotaxy is present in Calotropis and sunflower plants.
C. Whorled phyllotaxy is present in Alstonia and guava.
D. More than two options are incorrect.

Answer

To determine which statement is incorrect, we will analyze each statement one by one.

### Step-by-Step Solution:

1. **Analyze the First Statement**:
- The statement claims that alternate phyllotaxy is present in China rose, mustard, and sunflower.
- **Definition**: In alternate phyllotaxy, a single leaf is present at each node.
- **Evaluation**: This statement is correct as all mentioned plants exhibit alternate phyllotaxy.

2. **Analyze the Second Statement**:
- The statement claims that opposite phyllotaxy is present in Callotropis and sunflower.
- **Definition**: In opposite phyllotaxy, a pair of leaves arises at each node.
- **Evaluation**: This statement is also correct because Callotropis exhibits opposite phyllotaxy, while sunflowers can have both alternate and opposite phyllotaxy depending on the species.

3. **Analyze the Third Statement**:
- The statement claims that whorled phyllotaxy is present in Alstonia and Guava.
- **Definition**: Whorled phyllotaxy means more than two leaves arise at each node, forming a whorl or circle.
- **Evaluation**: This statement is incorrect because Alstonia does exhibit whorled phyllotaxy, but Guava does not; Guava has opposite phyllotaxy.

4. **Conclusion**:
- The incorrect statement is the third one, which states that whorled phyllotaxy is present in both Alstonia and Guava.

### Final Answer:
The incorrect statement is the third one: "Whorled phyllotaxy is present in Alstonia and Guava."
