Which of the following diagram represents axile placentation?

Options

A.
B.
C.
D.

Answer

To determine which diagram represents axile placentation, we need to understand what placentation is and the different types of placentation found in flowering plants.

### Step-by-Step Solution:

1. **Understanding Placentation**:
- Placentation refers to the arrangement of ovules within the ovary of a flower. It is crucial to identify the type of placentation to answer the question correctly.

2. **Identifying Types of Placentation**:
- There are several types of placentation, including:
- **Basal Placentation**: Ovules are attached at the base of the ovary.
- **Free Central Placentation**: Ovules are situated in the center of the ovary, with no septa dividing them.
- **Parietal Placentation**: Ovules are attached to the walls of the ovary.
- **Axile Placentation**: Ovules are attached to a central column (the placenta) in a multi-locular ovary.

3. **Analyzing the Options**:
- The first option represents **Basal Placentation** (wrong).
- The second option depicts **Free Central Placentation** (wrong).
- The third option shows **Parietal Placentation** (wrong).
- The fourth option illustrates **Axile Placentation**, characterized by multiple locules with ovules attached to a central axis (correct).

4. **Conclusion**:
- The correct answer is the last option, which represents axile placentation.
