Placentation of mustard plant is :-

Options

A. Parietal
B. Axial
C. Basal
D. Marginal

Answer

To determine the type of placentation in the mustard plant, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Term "Placentation":**
- Placentation refers to the arrangement of ovules within the ovary of a flower. The ovules are attached to the ovary wall by a structure called the placenta.

2. **Identify Different Types of Placentation:**
- There are several types of placentation:
- **Parietal:** Ovules are attached to the inner wall of a unilocular ovary or to the walls of locules in a multilocular ovary.
- **Axial:** Ovules are arranged along the central axis of the ovary, typically in a multilocular structure.
- **Basal:** The placenta is located at the base of the ovary, usually with a single ovule.
- **Marginal:** Ovules are arranged along the margin of a single locule.

3. **Focus on the Mustard Plant:**
- The mustard plant is known for having a specific type of placentation.

4. **Determine the Type of Placentation in Mustard:**
- The type of placentation found in the mustard plant is **parietal placentation**. In this type, the ovules are attached to the walls of the ovary.

5. **Conclusion:**
- Therefore, the placentation of the mustard plant is parietal.

### Final Answer:
The placentation of the mustard plant is **parietal**.
