Explanation:

Anaphase is a stage of mitosis. Sister chromatids, which are identical copies of a chromosome, separate at the centromere. Spindle fibers then pull these separated chromatids to opposite poles of the cell. Option B describes metaphase, option C describes telophase, and option D describes prophase.

A. Sister chromatids separate and move toward opposite poles.
