Solution
The correct option is B Prophase and metaphase
The DNA replication takes place in the S-phase of interphase. The replicated DNA is present in the form of sister chromatids attached to the centromere of the same chromosome. The condensation of the chromosomes take place in the prophase and the homologous chromosomes get aligned together to form the bivalent. These structures are present in the prophase and metaphase. In the anaphase, they get separated by migrating towards the opposite poles. Thus, the correct answer is option A.
