Solution

The correct option is B corona radiata


Well-developed and matured ova contains three layers: oocyte, zona pellucida and corona radiata.

Corona radiata is the innermost layer of the Graafian follicle which is present next to zona pellucida that supplies important protein to the cell.

The germinal epithelium of the ovary is the cell that gives rise to follicular cells which surrounded the primordial germ cell to form the primordial follicle.

The space between zona pellucida and the cell membrane of an oocyte is called perivitelline space.

Granulosa cells of the ovulatory follicle are an exclusive source of estrogen in the follicular phase of the ovarian cycle. It functions as an endocrine structure that produces estrogen hormone during the follicular phase of ovarian cycle.
