Solution

The correct option is C
Anaphase I

During anaphase I, two out of each tetrad of chromatids of a chromosome move as a unit to one of the poles of the spindle. The other two chromatids of its homologue migrate to the opposite pole. Therefore, rather than the chromatids of a chromosome, the homologous chromosomes of each pair are separated.
