Answer:
The correct answer would be anaphase.
Anaphase is the third stage of the mitotic or M phase.
During this phase, the sister chromatids of the chromosomes are pulled apart to the opposite ends of the dividing cell.
The sister chromatids are pulled apart with the help of spindle fibers.
The cell also elongates during this phase so that it can accommodate the separating chromatids.
This phase is followed by telophase during the parent nucleus is divided into the two daughter nuclei.
