Concept:Mitosis follows a fixed order: prophase, metaphase, anaphase, then cytokinesis.
Explanation:The correct sequence is based on the stages of mitosis.
First, chromosomes become visible during prophase, which is event II.
Next, chromosomes align at the equator during metaphase, which is event III.
Then, chromatids separate and move to opposite poles during anaphase, which is event I.
Finally, the cytoplasm divides during cytokinesis, which is event IV.
Thus, the order is II → III → I → IV.
Answer:B. II, III, I, IV
