Solution

The correct option is D Both Assertion and Reason are incorrect
During metaphase II the chromosomes align at the equator. The microtubules from opposite poles of the spindle get attached to the kinetochores of sister chromatids. Anaphase II begins with the simultaneous splitting of the centromere of each chromosome into two. Consequently, the daughter Chromosomes move towards the opposite poles of the cell.
