Solution

The correct option is B Golgi body and endoplasmic reticulum are reformed
In mitosis, anaphase is the stage of chromosome splitting at the centromere. Centromere divides and the two sister chromatids migrate towards opposite poles. The movement of chromatids is aided by spindle fibers. Golgi bodies and other cell organelles do not reappear in anaphase stage but reappear later on after cytokinesis.
So, the correct answer is option A.
