E) the G₀ phase is occurring.
Cleavage Furrow
The indentation that appears in a cell's surface when it is about to divide, leading to cytokinesis in animal cells.
Cytokinesis
The process during cell division in which the cytoplasm of a parent cell is divided into two daughter cells, following the separation of the cell nucleus during mitosis or meiosis.
Mitosis
A form of cellular division leading to the creation of two offspring cells, each possessing an identical number and type of chromosomes to that of the original nucleus, commonly seen in regular tissue development.

Final Answer :
B
Explanation :
A cleavage furrow is a physical indentation that appears in the plasma membrane of animal cells during cell division, specifically during cytokinesis. The furrow is formed when a contractile ring made of actin filaments and myosin II contracts, pulling the plasma membrane inward and separating the two daughter cells. Therefore, the appearance of a cleavage furrow indicates that cytokinesis is occurring, and the cell is in the process of dividing into two identical, genetically identical daughter cells.
