• B. Anaphase
• C. Prophase
• D. Telophase

Answer: (B)

Verified step by step guidance

1. Recall the main phases of mitosis: Prophase, Metaphase, Anaphase, and Telophase.
2. Understand that during Prophase, chromosomes condense and the mitotic spindle begins to form.
3. During Metaphase, chromosomes align at the metaphase plate, but sister chromatids are still attached.
4. In Anaphase, the key event is the separation of sister chromatids, which are pulled toward opposite poles of the cell.
5. Finally, during Telophase, the chromatids arrive at the poles and begin to decondense, leading to the formation of two nuclei.
