The correct option is
D Occurs only during interphase
Cleavage
is basically the process of division of a single-celled zygote into a multicellular
blastocyst that further undergoes implantation and development to form a fetus.
Restoration of the cell size and the nucleocytoplasmic ratio characteristic of
the species also take place in cleavage. Also, during cleavage, very little
growth occurs between the stages. But no actual growth occurs during this
process as the initial and final stages are of almost the same size.So, the correct answer is 'occurs only during interphase'.
