The Process of Fertilisation in the Sea Urchin Involves

The process of fertilisation in the sea urchin involves

A) binding of the sperm to the egg; release of hydrolytic enzymes from the sperm; movement of the whole sperm into the egg cytoplasm.
B) formation of the acrosomal process to the vitelline membrane; release of hydrolytic enzymes from the sperm; penetration of the sperm head into the cytoplasm of the egg.
C) binding of the sperm to the plasma membrane of the egg; release of hydrolytic enzymes from the sperm; penetration of the sperm head into the cytoplasm of the egg.
D) binding of the sperm to the plasma membrane of the egg; release of hydrolytic enzymes from the sperm; movement of the whole sperm into the egg cytoplasm.
E) interaction between the sperm and the jelly coat of the egg; release of hydrolytic enzymes from the sperm; movement of the sperm head into the egg cytoplasm.
