Solution
The correct option is C First anaphase of meiosis Anaphase I begins when 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. It has to be noted that in anaphase I the sister chromatids remain attached at their centromeres and move together toward the poles.
So the correct option is 'first anaphase of meiosis'.
