A. the acrosome migrates towards the posterior end of the spermatid because its hydrolytic enzymes will be needed for digestion of the excessive cytoplasm around the flagella of the developing sperm
B. the acrosome migrates towards the anterior end of the spermatid because its hydrolytic enzymes will be needed for penetration when the sperm contacts the egg during fertilization
