Answer

To solve the question of selecting the incorrect pairing, we will analyze each option provided in the question step by step.

### Step-by-Step Solution:

1. **Understanding Apocarpus**:
- **Definition**: Apocarpus refers to a condition where multiple carpels are present and are free from each other.
- **Examples**: Lotus and rose are known to have apocarpous flowers.
- **Conclusion**: The pairing "Apocarpus - Carpal free, Lotus and Rose" is correct.

2. **Understanding Syncarpus**:
- **Definition**: Syncarpus refers to a condition where multiple carpels are fused together.
- **Examples**: Mustard and tomato exhibit syncarpous flowers.
- **Conclusion**: The pairing "Syncarpus - Carpus fused, Mustard and Tomato" is correct.

3. **Understanding Exile Placentation**:
- **Definition**: Exile placentation is where the placenta is located on the central axis of a multiocular ovary, with ovules attached to it.
- **Examples**: Lemon and tomato both show exile placentation.
- **Conclusion**: The pairing "Exile, Placentation, Lemon and Tomato" is correct.

4. **Understanding False Septum**:
- **Definition**: A false septum is a thin membrane that can create the appearance of additional chambers in an ovary.
- **Examples**: Mustard exhibits false septum formation, but Dianthus has free central placentation where ovules are attached to a central axis without any septum.
- **Conclusion**: The pairing "Formation of false septum, Mustard and Dianthus" is incorrect because Dianthus does not exhibit false septum formation.

### Final Answer:
The incorrect pairing is **D: Formation of false septum, Mustard and Dianthus**.
