The correct Answer is:
**Step-by-Step Solution:** 1. **Understanding Corona Radiata**: The corona radiata is a layer of cells that surrounds the egg (oocyte) in the ovarian follicle. It is crucial for the egg's protection and nourishment. 2. **Location of Corona Radiata**: The corona radiata is located adjacent to the zona pellucida, which is the glycoprotein layer surrounding the egg. 3. **Function of Corona Radiata**: The primary function of the corona radiata is to provide vital proteins necessary for the fertilization of the egg. These proteins support the egg's development and interaction with sperm. 4. **Origin of Corona Radiata**: The cells of the corona radiata are derived from squamous granulosa cells that are present during the primordial stage of follicular development. As the follicle matures, these cells transition to a cuboidal shape and are referred to as granulosa cells. 5. **Chemical Composition**: The zona pellucida secretes mucopolysaccharides, which are essential for holding the corona radiata in place. These mucopolysaccharides provide structural support and facilitate the interaction between the egg and sperm. 6. **Identifying the Correct Answer**: Among the given options (mucopolysaccharide, oligosaccharide, lipopolysaccharide, lipoprotein), the correct answer is **mucopolysaccharide** as it is the substance that holds the corona radiata. **Final Answer**: Mucopolysaccharide holds the corona radiata. ---
