In a newly fertilized egg, the vitelline layer lifts away from the egg and hardens to form a fertilization envelope.
Therefore, the correct answer is Option A.
<h3>What is vitelline layer?</h3>
- Vitelline layer or vitelline membrane (VM) is a structure that surrounds the outer surface of the plasma membrane of an egg or ovum. In some organisms (e.g.: birds), the vitelline layer surrounds the extracellular yolk and the ovum.
- It is multilayered and functions to protect and give shape to the egg yolk and separate it from the egg white.
- VM consists of protein fibers and protein receptors necessary for sperm binding.
- As its function is to provide support and protection to the yolk, after fertilization, the vitelline layer gets hardened and separated from the yolk to form fertilization envelope.
