A) first cell division → synthesis of embryo's DNA begins → acrosomal reaction → cortical reaction.
B) cortical reaction → synthesis of embryo's DNA begins → acrosomal reaction → first cell division
C) cortical reaction → acrosomal reaction → first cell division → synthesis of embryo's DNA begins
D) first cell division → synthesis of embryo's DNA begins → acrosomal reaction → cortical reaction
E) acrosomal reaction → cortical reaction → synthesis of embryo's DNA begins → first cell division
