The correct Answer is:
**Step-by-Step Solution:** 1. **Understanding the Structure of the Ovum**: The ovum, or egg cell, is surrounded by several layers that provide protection and nutrition. These layers are important for the ovum's development and function. 2. **Identifying the Layers**: The main layers surrounding the ovum include: - **Thica Externa**: The outermost layer. - **Thica Interna**: The layer just beneath the thica externa. - **Granulosa Layer**: This layer is in contact with the ovum and plays a crucial role in its nourishment. - **Corona Radiata**: The outer layer of the ovum that is in contact with the granulosa layer. - **Zona Pellucida**: The membrane that directly surrounds the ovum and is crucial for fertilization. 3. **Determining the Membrane Just Outside the Granulosa Layer**: The question specifically asks for the membrane that is investing the ovum just outside the membrana granulosa. 4. **Identifying the Correct Answer**: The membrane that is located just outside the granulosa layer is the **Zona Pellucida**. This layer is essential for protecting the ovum and facilitating sperm binding during fertilization. 5. **Conclusion**: Therefore, the correct answer to the question is the **Zona Pellucida**. ---
