Solution
The correct option is D Anaphase 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.
