Question

during the highlighted phase of mitosis, the chromosomes are

aligned in the center of the cell

moving away from each other toward opposite poles of the cell

attaching to mitotic spindle microtubules at the centromere

returning to chromatin form

Explanation:

In mitosis, during anaphase, chromosomes move away from each other towards opposite poles of the cell. If the highlighted phase is anaphase (assuming based on the options), this is the key event. Chromosomes align in the center during metaphase, attach to micro - tubules in prometaphase, and return to chromatin form in telophase.

Answer:

B. moving away from each other toward opposite poles of the cell
