The correct option is
C Cytokinesis
Cytokinesis involves the division of cytoplasm after karyokinesis. It mainly starts at anaphase but continues till telophase. During telophase, a nuclear membrane forms around each set of chromosomes to separate the nuclear DNA from the cytoplasm. The chromosomes begin to uncoil, which makes them diffuse and less compact. Along with telophase, the cell undergoes a separate process called cytokinesis that divides the cytoplasm of the parental cell into two daughter cells. In the animal cell the cytokinesis takes place by formation of furrow while, phragmoplast formation takes place in plants.
So, the correct answer is option C.
