Select the correct match (Regarding ovary)

Options

A. Pisum- Marginal- Bilocular
B. Citrus – Axile - Trilocular
C. Argemone - Parietal - Bilocular
D. Dianthus -- Basal - Unilocular

Answer

To solve the question regarding the correct match related to the ovary, we need to analyze each option provided and determine their correctness based on the characteristics of placentation and locules.

### Step-by-Step Solution:

1. **Understand the Terms**:
- **Ovary**: The part of the flower that contains ovules and develops into fruit after fertilization.
- **Placentation**: The arrangement of ovules within the ovary.
- **Locule**: A chamber within the ovary that contains ovules.

2. **Evaluate Each Option**:
- **Option 1: P-sum (Marginal and Bilocular)**:
- Marginal placentation is correct for P-sum (pea plant) as ovules are located along the margin.
- However, it is unilocular (one chamber), not bilocular (two chambers).
- **Conclusion**: Incorrect match.

- **Option 2: Citrus (Exile Placentation)**:
- Exile placentation refers to the arrangement where ovules are attached to the central axis.
- Citrus is typically trilocular (three chambers), but it has two locules in each chamber, which makes this description misleading.
- **Conclusion**: Incorrect match.

- **Option 3: Argamone (Parietal and Bilocular)**:
- Parietal placentation means ovules are attached to the walls of the ovary.
- Argamone indeed has bilocular (two chambers) structure.
- **Conclusion**: Correct match.

- **Option 4: Dianthus (Basal and Unilocular)**:
- Basal placentation means ovules are attached at the base of the ovary.
- However, Dianthus is bilocular (two chambers), not unilocular (one chamber).
- **Conclusion**: Incorrect match.

3. **Final Decision**:
- After evaluating all options, the correct match regarding the ovary is **Option 3: Argamone (Parietal and Bilocular)**.
