None of the above.

Answer 1

The end of the metaphase and beginning of anaphase is marked by the splitting of centromere so that two chromatids (In fact complete chromosomes) start moving to the opposite pole during anaphase. Thus the chromosomes divide at anaphase by the splitting of centromere.

so it's Pulled apart at the centromere (5th)
