Solution

The correct option is A Zona pellucida
Zona pellucida in an antral follicle is acellular, meaning it is not made of cells. The zona pellucida is a glycoprotein layer surrounding the plasma membrane of mammalian oocytes. It is a vital constitutive part of the oocyte.

The granulosa, theca interna and stroma layers are all made of cells and hence are cellular in nature.
