• D. Anaphase

Answer: (C)

Verified step by step guidance

1. Understand the stages of mitosis: Mitosis is divided into several phases: prophase, metaphase, anaphase, and telophase.
2. Identify the key events in each phase: In prophase, chromosomes condense and become visible. In metaphase, chromosomes align at the cell's equatorial plane. In anaphase, sister chromatids separate and move to opposite poles. In telophase, the cell prepares to divide into two.
3. Focus on metaphase: During metaphase, the chromosomes, which consist of two sister chromatids, are aligned along the equatorial plane of the cell, also known as the metaphase plate.
4. Recognize the role of the spindle apparatus: The spindle fibers attach to the centromeres of the sister chromatids and help align them at the metaphase plate.
5. Conclude with the correct phase: Based on the alignment of sister chromatids along the equatorial plane, the correct phase of mitosis is metaphase.
