Find the correctly matched pair

Options

A. Basal- Marigold
B. Free central- Argemone
C. Parietal-Primrose
D. Axile-Pea

Answer

To solve the question of finding the correctly matched pair regarding placentation in flowers, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Terms**:
- The question presents different types of placentation: basal, free central, parietal, and exiled, along with corresponding flower examples: marigold, argument, primrose, and pea.

2. **Identifying Placenta Types**:
- **Basal Placenta**: This type of placentation occurs when the ovules are attached at the base of the ovary.
- **Free Central Placenta**: In this type, the ovules are attached to a central column in the ovary, not to the walls.
- **Parietal Placenta**: Here, the ovules are attached to the walls of the ovary.
- **Exiled Placenta**: This type involves ovules attached along the central axis of the ovary.

3. **Matching with Examples**:
- **Basal Placenta with Marigold**: This is a correct match.
- **Free Central Placenta with Argument**: This is incorrect; free central placentation is found in plants like Dianthus.
- **Parietal Placenta with Primrose**: This is incorrect; parietal placentation is found in plants like Papaya and Brassica.
- **Exiled Placenta with Pea**: This is incorrect; exiled placentation is found in Citrus and Tomato. Pea has marginal placentation.

4. **Conclusion**:
- The only correctly matched pair is **Basal Placenta with Marigold**.

### Final Answer:
The correctly matched pair is **Basal Placenta with Marigold**.
