C Correct answer
Explanation

The acrosome is a specialised structure that is inside the tip of the sperm cell. It is derived from the Golgi complex during the maturation of the sperm. It is basically a storage vesicle that contains hydrolytic enzymes that digest proteins and complex sugars. The contents of the acrosome are secreted once the sperm makes contact with the egg. These enzymes will break down the zona pellucida, forming a thin path that allows the sperm to approach the egg and fuse with its cytoplasm.
