As we already discussed in Events of Fertilization -

Fertilizin-Antifertilizin Reaction:

  • The sperm can fertilize an ovum only they are able to secrete the chemical hyaluronidase and possess a surface protein called antifertilizin (composed of acidic amino acid). 
  • The ovum secretes a chemical named fertilizin (composed of glycoprotein = monosaccharides + amino acids). 
  • The fertilizin interacts with the antifertilizin of the sperm and this interaction makes the sperm to stick to the surface of the ovum. 
     

Hence, the correct option is (d).
