Read the following matches regarding the placentation
(i) Primrose - Free central
(ii) Pea - Marginal
(iii) Marigold - Basal
(iv) Mustard - Axile
Which of these are correct ?

Options

A. (i), (ii) and (iii)
B. (ii), (iii) and (iv)
C. (i), (iii) and (iv)
D. All are correct.

Answer

To determine the correctness of the matches regarding the placentation in the given plants, we will analyze each plant and its corresponding type of placentation step by step.

### Step-by-Step Solution:

1. **Primrose - Free Central**:
- In Primrose, the ovules are attached to a central column in the ovary without any septa. This type of placentation is known as free central placentation.
- **Conclusion**: This match is **correct**.

2. **Pea - Marginal**:
- In Pea plants, the ovules are arranged along the margin of the ovary. This is characteristic of marginal placentation.
- **Conclusion**: This match is **correct**.

3. **Marigold - Basal**:
- In Marigold, the ovules are situated at the base of the ovary. This type of arrangement is referred to as basal placentation.
- **Conclusion**: This match is **correct**.

4. **Mustard - Axile**:
- In Mustard (Brassicaceae family), the ovules are attached to a central axis and are arranged in two or more locules, which is known as axile placentation. However, the video transcript incorrectly states it as parietal placentation. The correct classification for Mustard is indeed axile placentation.
- **Conclusion**: This match is **correct**.

### Final Conclusion:
All four matches are correct:
- Primrose - Free Central: **Correct**
- Pea - Marginal: **Correct**
- Marigold - Basal: **Correct**
- Mustard - Axile: **Correct**
