Verified by Experts

The correct Answer is:
B
(b) The progressive division of cells during enbryonic growth is called cleavage. It is not accompanied by increase in the overall size of embryo.
The first cleavage occurs in human zygote about 30 hours after fertilisation. It is holoblastic (complete) and gives rise to the blastomeres-one of which is slightly larger than the other.
