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

Answer: (D)

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. Recognize that during Metaphase, chromosomes align along the metaphase plate, which is the cell's equatorial plane.
4. Know that during Anaphase, sister chromatids are pulled apart toward opposite poles of the cell.
5. Remember that during Telophase, the chromosomes reach the poles and the nuclear envelope re-forms, completing mitosis.
