Solution

The correct option is C It agglutinates sperm.
The fertilizin (gynogamone) is a chemical substance secreted by ovum. It is glyco proteinaceous in nature and serves to attract the sperm, i.e., agglutinate the sperms. Antifertilizin (androgamone) is a chemical substance secreted by the sperm which is an acid protein. The reaction between fertilizin and anti-fertilizin is species specific.
