Solution

The correct option is A Movement of chromosomes towards poles
Centromere is present in every cell. It is a specific DNA sequence in a chromosome. It is specifically useful in the process of cell division. During mitosis, the spindle fibres attach to the centromeres via kinetochore and all the chromosomes are arranged in an equatoral plane. After this, the chromosomes move towards their respective poles and cell division takes place.
So, option A is the correct answer.
