The glycoprotein layer between oocytes and cuboidal cells in ovary of rabbit is

Options

A. Membrana granulosa
B. Zona pellucida
C. Corpus luteum
D. Zona reticulata

Explanation

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks for the glycoprotein layer that exists between oocytes and cuboidal cells in the ovary of a rabbit.

2. **Identifying Key Terms**:
- Oocytes: These are the immature eggs found in the ovaries.
- Cuboidal cells: These are the follicular cells that surround the oocyte and are involved in the development of ovarian follicles.

3. **Recognizing the Structure**: The glycoprotein layer in question is known as the "zona pellucida." This layer is crucial as it separates the oocyte from the surrounding follicular cells (cuboidal cells).

4. **Function of the Zona Pellucida**: The zona pellucida plays a significant role in fertilization by providing a protective barrier around the oocyte and facilitating sperm binding.

5. **Conclusion**: Therefore, the glycoprotein layer between oocytes and cuboidal cells in the ovary of a rabbit is the zona pellucida.

**Final Answer**: The glycoprotein layer between oocytes and cuboidal cells in the ovary of a rabbit is the **zona pellucida**.
