Select the CORRECT pair from the following.

Options

A. Marginal placentation - China rose, pea
B. Parietal placentation - Mustard , Marigold
C. Free central placentation - Dianthus , primrose
D. Basal placentation - Tomato , Lemon

Answer

To solve the question, we need to identify the correct pair of placentation types and their corresponding examples from the options provided. Let's analyze each pair step by step.

### Step 1: Understand the Types of Placentation
1. **Marginal Placentation**: Ovules are arranged along a ridge on the ventral suture of the ovary.
2. **Parietal Placentation**: Ovules are attached to the inner wall of the ovary.
3. **Free-central Placentation**: Ovules are attached to a central column, with no septa present.
4. **Basal Placentation**: Ovules are attached at the base of the ovary.

### Step 2: Analyze Each Pair
1. **Marginal, Placentation, China Rose, Pea**:
- China Rose (Hibiscus) has **exile placentation**.
- Pea has **marginal placentation**.
- **This pair is incorrect**.

2. **Paretial, Mustard and Marigold**:
- Mustard has **parietal placentation**.
- Marigold has **basal placentation**.
- **This pair is incorrect**.

3. **Free-central, Dihensis and Prime Rose**:
- Dihensis is not a recognized plant, but if we consider "Dianthus" (which is likely intended), it has **free-central placentation**.
- Primrose (Primula) also has **free-central placentation**.
- **This pair is correct**.

4. **Basal, Tomato and Lemon**:
- Tomato has **exile placentation**.
- Lemon has **exile placentation**.
- **This pair is incorrect**.

### Conclusion
The only correct pair from the options given is **Free-central, Dihensis and Prime Rose**.

### Final Answer
The correct pair is **Free-central, Dihensis and Prime Rose**.
