Exam answer
ANAPHASE.
Explanation
Identify the stage from ONE visible feature, and there is a different one for each: PROPHASE — chromosomes visible but scattered; the nuclear membrane is breaking down METAPHASE — chromosomes LINED UP at the equator in one plane ANAPHASE — chromatids SEPARATED and MOVING TOWARDS OPPOSITE POLES, drawn in a V or J shape as the spindle drags them by the centromere TELOPHASE — two groups of chromosomes at the poles; nuclear membranes re-forming
The V-shaped chromosomes being pulled apart are unmistakable, because nothing else in the cycle looks like that.
