Arrange the following cell layers/structures around the female gamete, from outer to inner side : A. Zona pellucida B. Perivitelline space C. Corona radiata D. Plasma membrane of ovum Choose the correct answer from the options given below :

Step-by-step solution

The mature female gamete (ovum) is surrounded by several layers. From the outermost to the innermost side, the arrangement is as follows: Corona radiata: The outermost layer consisting of follicle cells. Zona pellucida: A non-cellular glycoprotein layer situated just inside the corona radiata. Perivitelline space: The narrow space between the zona pellucida and the plasma membrane of the ovum. Plasma membrane of ovum (Oolemma): The innermost boundary enclosing the cytoplasm of the ovum. Therefore, the correct seque
