C. During M Phase.

M phase - When a cell is in the M phase, it divides, first through nuclear division (mitosis), then through cytoplasmic division (cytokinesis). The DNA is replicated in the earlier S phase, and cohesins keep each replicated chromosome's two copies (known as sister chromatids) bound to one another.

Mitosis is divided into four stages

  • Prophase
  • Metaphase
  • Anaphase
  • Telophase

After metaphase , in which the chromosomes align at the equator, comes the Anaphase in which when the sister chromatids of each chromosome separate and move to the opposing poles of the cell. This separation results from the breakdown of cohesin, the protein that held the sister chromatids together during prophase, by enzymes. Every chromatid splits out to produce a separate chromosome.

Hence, during Anaphase of M phase sister chromatids move apart.
