Solution

The correct option is B Size of cell decreases
Cleavage is a succession of rapid mitotic cell division of zygote after fertilization resulting in the formation of multicellular blastula. In cleavage division, the interphase is short and does not involve growth. Thus, the resulting blastomeres become smaller in size as their number increases.
