Solution

The correct option is B Anaphase II
In anaphase II, the centromeres separate and the sister chromatids—now individual chromosomes—move toward the opposite poles of the cell. 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 'Anaphase II'.
