Solution
The correct option is B Anaphase I of Meiosis I
During Anaphase I the two chromosomes of each bivalent (tetrad) separate and start moving toward opposite poles of the cell as a result of the action of the spindle. In anaphase I the sister chromatids remain attached at their centromeres and move together toward the poles. During Anaphase II, the centromere splits and sister chromatids separate and the daughter cells get one chromatid each.
