The correct option is
A Cleavage
Cleavage
is the term used for repeated mitotic divisions that take place during the
growth of an embryo. A single-celled embryo undergoes successive rounds of division
to form a blastocyst which is 16-celled. No actual growth occurs during this
process as the initial and final stages are of almost the same size of almost the same size. Also, during
cleavage, very little growth occurs between the stages or during interphase.So, the correct answer is 'Cleavage'.
