Solution

The correct option is B
Movement of chromosomes towards poles

Centromeres are required for chromosome separation during cell division. They are the attachment points for microtubules which pull duplicate chromosomes towards the opposite poles of the cell before it divides. This separation ensures that each daughter cell will receive a full set of chromosomes.
