In which stage do the chromatids get separated and move toward opposite ends of the cell?

The correct answer is "anaphase".

Explanation:

The anaphase is the third phase of mitosis at which the chromatids get separated and move toward opposite ends of the cell. This phase takes place once the genetic material has been replicated and right before the cells are separated into the two daughter cells. Other important feature of the anaphase is that chromosomes reach their maximum condensation state, which make them able to separate into the chromatids.

the answer to your great question is telophase
