Solution
The correct option is B corona radiata
During follicle development, the oocyte is surrounded by granulosa cells. These cells rest on the basement membrane further surrounded by theca interna and theca externa. Theca interna is the secretory layer and theca externa is the connective tissue layer. The secondary oocyte forms a new membrane made of glycoprotein around itself called zona pellucida. Corona radiata lies outside zona pellucida.
The perivitelline space is the gap between the plasma membrane and the zona pellucida of oocytes. It lies inside the zona pellucida
Germinal epithelium is simple cuboidal cells of sex organs that give rise to gametes.
