Solution

The correct option is B Anaphase II
Each chromosome composed of one chromatid in anaphase II because the centromeres separate, and the two chromatids of each chromosome move to opposite poles on the spindle. The separated chromatids are now called chromosomes in their own right.
So, the correct answer is option B.
