Letter b (found in the image above) represents a cell in which phase? a) prophase b) metaphase c) anaphase d) interphase (ignore highlighted answer, was just a educated guess.)

Anaphase because the chromosomes are moving away (Ana- Away)

The correct answer is option C which is anaphase.

Explanation:In the given picture, C shows a cell in which two poles of cells have spindal fibers which are separated from each other, moving to the opposite poles and they have daughter chromatids attached to these fibers.And in anaphase of cell cycle, spindle fibers return to there respective poles, breaking the centromere, forming the cluster of threads on opposite poles.Hence given letter B in picture shows anaphase.
