(B) Cleavage is a series of rapid mitotic cell divisions of the zygote following fertilization.During cleavage,the total volume of the embryo remains constant because there is no growth phase ($G_1$ or $G_2$ phases) between the divisions.As the number of cells (blastomeres) increases,the size of each individual cell decreases significantly with each successive division.Therefore,the correct statement is that the size of the cells decreases.
