• D. Telophase

Answer: (B)

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 characteristics of each phase: In prophase, chromosomes condense and become visible. In metaphase, chromosomes line up at the cell's equatorial plane. In anaphase, sister chromatids are pulled apart. In telophase, the cell prepares to divide.
3. Focus on the phase where chromosomes are aligned: During metaphase, the chromosomes are aligned at the metaphase plate, which is the center of the cell.
4. Recognize the role of the spindle fibers: During metaphase, spindle fibers attach to the centromeres of the chromosomes to ensure they are properly aligned.
5. Conclude that the phase where condensed chromosomes are lined up in the center of the cell is metaphase.
