I think the correct answer from the choices listed above is the last option. It is the M phase the period of cell life when it is conducting cell division. Mitosis and cytokinesis together define the mitotic (M<span>) </span>phase<span>of an animal cell cycle. Hope this answers the question. </span>
M phase or mitotic phase is a period of the cell cycle in which karyokinesis and cytokinesis take place.
Karyokinesis refers to the division of the nucleus of a cell. It occurs in four stages namely prophase, metaphase, telophase, and anaphase. It results in the division of nuclear content (replicated chromosomes) of a parent nucleus into two daughter nuclei.
It is followed by cytokinesis during which cell membrane, cytoplasm, cell organelle, and daughter nuclei are divided into two daughter cells.
