Match the following mechanism of polyspermy (Column I) with events (Column II).

Column I	Column II
A. Fast block to polyspermy	i. chemicals from the fusing sperm cytoplasm alter the sodium ion (Na+) channels on the membrane
B. Slow block to polyspermy	ii. enzyme cortical granule serine protease, cleaves the protein posts that connect the vitelline envelope
	iii the concentration of free Ca2+ in the egg cytoplasm increases
	iv. an electric change in the egg cell membrane
	v. the concentration of free Na+ in the egg cytoplasm increases
