C Correct answer
Explanation

The rate of cell division in early cleavage cells is very high. So in these cells, cell cycle consists of only S and M phases. During S phase, cells synthesise the necessary materials for division and then, they proceeds towards the mitotic division that is the M phase. It is actually a time saving procedure for producing huge numbers of cells in shorter time span during early cleavage.
