Anaphase -The shortest stage of mitosis. The centromeres divide, and the sister chromatids of each chromosome are pulled apart - or 'disjoin' - and move to the opposite ends of the cell, pulled by spindle fibres attached to the kinetochore regions.

The correct answer is option A - Anaphase.
Explanation:
Mitosis is a process of cell division that involves the division of the genetic material within the nucleus of a cell. The process is divided into four stages - prophase, metaphase, anaphase, and telophase.
During the anaphase stage, the sister chromatids separate from each other and move towards opposite poles of the cell. This is achieved through the action of spindle fibers that attach to the centromere of each chromatid.
The chromatids are pulled towards the poles of the cell by the shortening of the spindle fibers. Once the chromatids have reached their respective poles, they are considered individual chromosomes.
Anaphase is a critical stage of mitosis because it ensures that each daughter cell receives a complete set of chromosomes. Any errors in this stage can result in chromosomal abnormalities and genetic disorders.
In summary, the anaphase stage of mitosis is where chromatids separate and pass to different poles, ensuring the proper distribution of genetic material to daughter cells.
