Solution

The correct option is C Antifertilizin
Antifertilizin is a surface protein present on the sperm. Along with hyaluronidase enzyme secreted by the acrosome, it helps in fertilising the egg.
The ovum secretes a protein called fertilizin, which is prevents sperms from entering it by clumping and inactivating them.
