A
cell cycle
B
interphase
C
mitosis
D
cytokinesis
Explanation: 

Detailed explanation-1: -Mitosis is a process of nuclear division in eukaryotic cells that occurs when a parent cell divides to produce two identical daughter cells. During cell division, mitosis refers specifically to the separation of the duplicated genetic material carried in the nucleus.

Detailed explanation-2: -A membrane forms around each set of chromosomes to create two new nuclei. The single cell then pinches in the middle to form two separate daughter cells each containing a full set of chromosomes within a nucleus. This process is known as cytokinesis.

Detailed explanation-3: -Karyokinesis. Division of the nucleus during cell division is called karyokinesis and is followed by Cytokinesis, the division of the cell cytoplasm. Metakinesis is the separation of sister chromatids and their movement to opposite poles during anaphase stage of mitosis.
