Answer #1
  • b is the right answer

Fertilizin is a chemical substance which is secreted by the matured eggs that is ovum, and mainly composed of glycoproteins which is a combination of monosaccharides and aminoacids.

Sperm contains antifertilizin which is composed of acidic aminoacids on its surface and this fertilizin of an egg interacts with the antifertilizin of the same species causes the sperms stick to the egg surface

The capacity of sperm to fertilize the egg is called capacitation
