Solution

The correct option is A a and b are incorrect and c is correct
At the onset of anaphase, each chromosome arranged at the metaphase plate is split simultaneously and the two daughter chromatids, now referred to as chromosomes of the future daughter nuclei, begin their migration towards the two opposite poles.

Chromosomes move to spindle equator and get aligned along metaphase plate through spindle fibres to both poles during metaphase.
As each chromosome moves away from the equatorial plate, the centromere of each chromosome remains directed towards the pole.
