Shown below are 4 stages (A,B,C,D) (not in sequence) of a certain kind of cell division.
Nikitich [7]

The diagram below shows a cell undergoing mitosis (cell division). The correct order of the stages is B, C, D and A.

Mitosis is a type of cell division in which a parental cell divides to produce two genetically identical daughter cells.

In this case, an animal cell is undergone mitosis because the cell exhibits centrioles (only found in animal cells) and lacks cell walls (only present in plant cells).

The stages of mitosis include prophase, prometaphase, metaphase, anaphase, and telophase.
