Solution

The correct option is B Hyaluronidase
Surface of the sperm contains hyaluronidase enzyme. During entry of capacitated sperm into the ovum, acrosome of the sperm releases this enzyme. Hyaluronidase dissolves the hyaluronic acid present on the surface of the egg. This helps in penetration of sperm into the ovum.
Thus, the correct answer is option A.
