Answer

To solve the question "Choose the incorrect match," we will analyze each option provided in the question and determine whether the matches are correct or incorrect.

### Step-by-Step Solution:

1. **Exile Plantation and China Rose**:
- Exile plantation refers to a type of placentation where ovules are born at or around the center of a compound ovary.
- In the case of China Rose (Hibiscus rosa-sinensis), it is known for having a different type of placentation, specifically axile placentation.
- **Conclusion**: This match is incorrect.

2. **Free Central Placentation and Dianthus**:
- Free central placentation is characterized by ovules developing in a central column without the presence of septa.
- Dianthus (carnation) is indeed known to exhibit free central placentation.
- **Conclusion**: This match is correct.

3. **Poly Adolphous Stamen and Citrus**:
- Poly Adolphous Stamen refers to stamens that unite by their anthers into three or more groups.
- Citrus plants do not exhibit polyadelphous stamens; they typically have a different arrangement.
- **Conclusion**: This match is incorrect.

4. **Tetradynamous Condition of Stamen and Brassica**:
- Tetradynamous condition refers to a specific arrangement of stamens, where there are six stamens, four of which are longer than the other two.
- Brassica (mustard) is a classic example of a plant exhibiting this condition.
- **Conclusion**: This match is correct.

### Final Answer:
The incorrect matches are:
- Exile Plantation with China Rose
- Poly Adolphous Stamen with Citrus
