The division of cytoplasm is known as:

Correct option is D

The correct answer is (d) cytokinesis
Cytokinesis is the process in which the cytoplasm of a single eukaryotic cell is divided to form two daughter cells. It usually occurs after nuclear division (mitosis or meiosis, collectively known as karyokinesis), ensuring that each daughter cell receives a copy of the nucleus and an appropriate amount of cytoplasm and organelles. Cytokinesis begins during the final stages of nuclear division and involves a series of coordinated changes to the cell structure to accomplish division.
