Solution

The correct option is A
The chromatids joins at a constriction called centromere to form a complete chromosome. Centromere has disc shaped structures called kinetochores. The kinetochore is not the same as the centromere even though they may be present very close to each other. The kinetochore is associated with the organelle called centrosome, which helps in attaching to spindle fibres during cell division.
