Solution

The correct option is B Size of cells decrease
During cleavage, the zygote divides repeatedly to convert the large cytoplasmic mass into a large number of small blastomeres. It involves cell division without growth in size because cells continue to be retained within the zona pellucida. However, cell size decreases during cleavage.

So, the correct answer is 'Size of cells decrease'.
