Solution
The correct option is A Corona radiata
The zona pellucida (plural zonae pellucidae, also egg coat or pellucid zone) is a glycoprotein layer surrounding the plasma membrane of mammalian oocytes. It is a vital constitutive part of the oocyte. The corona radiata is composed of cells that care for the egg when it is emitted from the ovary. So, A cellular layer made up of glycoproteins within Graafian follicle around ovum prevents ectopic pregnancy is Corona Radiata.
