The correct answer is: B.anaphase.
Explanation:
During anaphase in mitosis, the sister chromatids (which are the identical copies of a chromosome) are pulled apart toward opposite poles of the cell. This separation is facilitated by the spindle fibers, which are attached to the centromeres of the chromatids. The process ensures that each daughter cell will receive an identical set of chromosomes.
