Placentation, in which ovules develop on the inner wall of the ovary or in peripheral part, is:

Options

A. Free central
B. Basal
C. Axile
D. Parietal

Answer

To solve the question regarding the type of placentation where ovules develop on the inner wall of the ovary or in the peripheral part, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Concept of Placentation**: Placentation refers to the arrangement of ovules within the ovary of a flower. Different types of placentation describe how and where these ovules are positioned.

2. **Identify the Types of Placentation**:
- **Free Central**: In this type, the ovules are attached to a central column and are free from the walls of the ovary. This is not the correct answer since the ovules are not on the inner wall.
- **Basal**: Here, a single ovule is attached at the base of the ovary. This does not fit the description given in the question.
- **Axile**: In axile placentation, the ovules are arranged in the center of a multilocular ovary. This does not match the description of ovules on the inner wall.
- **Parietal**: In parietal placentation, the ovules develop on the inner wall of the ovary or in the peripheral part. This matches the description provided in the question.

3. **Select the Correct Answer**: Based on the analysis, the type of placentation where ovules develop on the inner wall of the ovary or in the peripheral part is known as **Parietal placentation**.

### Final Answer:
The correct answer is **Parietal placentation**.
