Solution
The correct option is A Cleavage The mitotic division starts as the zygote moves through the isthmus of the oviduct called cleavage towards the uterus and forms 2, 4, 8 16 daughter cells called blastomeres. The embryo at 8-16 celled stage is called a morula. Thus the division starts at the cleavage.
