The arms of chromosome are known as chromatids. These arms are held together at a point called the centromere (or primary constriction). Centromere occurs any where along the length of chromosome. During ceIl division spindle fibres are attached to centromere and help in the movement of chromosomes towards the poles.

Towards the end of prophase (sometimes called prometaphase), the spindle extends between two poles positioned diametrically opposite one another in the cell and the chromosomes migrate toward the center of the spindle. In metaphase, the centromeres of each chromosome are aligned midway across the spindle on a plane called the equatorial plate.
At this time the centromeres are linked to the spindle fibers. Some of the spindle fibers do not form associations with any chromosomes and extend directly from one pole to the other. The centromeres are duplicated so that each chromatid becomes an independent chromosome and is attached to a spindle fiber connected to one of the two poles.
The onset of anaphase is characterized by the movement of the chromosomes toward opposite poles of the spindle.

The correct answer is option 'C', Movement of chromosomes towards poles.
Explanation:
Centromere is a specialized region of a chromosome that plays a crucial role in the proper segregation of chromosomes during cell division. The centromere is the point of attachment of the spindle fibers to the chromosome, which helps in the movement of chromosomes towards the poles during cell division.
The spindle fibers are responsible for the separation of the sister chromatids during cell division. The centromere helps in the attachment of these spindle fibers to the chromosomes, which is essential for the proper segregation of chromosomes during cell division. Without a centromere, the chromosomes would not be able to move towards the poles, and cell division would not occur properly.
Therefore, the correct answer is option 'C', Movement of chromosomes towards poles.
