A typical angiospermic microsporangium appears near circular in outline. It is generally surrounded by four wall layers. Find correct option with correct sequence from outside to inner side :-

Options

A. Epidermis, hypodermis, middle layer and tapetum
B. Epidermis, endothecium, middle layers and tapetum
C. Endothecium, epidermis, middle layers and tapetum
D. Endothecium, hypodermis, middle layers and tapetum

Answer

To solve the question regarding the correct sequence of the wall layers of a typical angiospermic microsporangium from the outside to the inner side, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Layers**: The microsporangium consists of four wall layers. We need to identify these layers correctly.

2. **List the Layers**: The four wall layers of the microsporangium are:
- Epidermis (outermost layer)
- Endothecium (second layer)
- Middle layers (third layer)
- Tapetum (innermost layer)

3. **Correct Sequence**: Based on the identification of the layers, the correct sequence from the outside to the inner side is:
- Epidermis
- Endothecium
- Middle layer
- Tapetum

4. **Conclusion**: Therefore, the correct option is: **Epidermis, Endothecium, Middle layer, and Tapetum**.
