Vedclass · Answer

(A) Immediately upon the entry of a spermatozoan into an oocyte,the oocyte membrane undergoes a rapid change in its electrical potential,known as depolarization. This change is associated with an increase in the permeability of the oocyte membrane to certain ions,which serves as a fast block to polyspermy. Therefore,the correct event is an increase in the permeability of the oocyte membrane.
