The correct answer reflects the sequential order of events that occur during mitosis, which is significant for cell division. Mitosis consists of specific phases that ensure the accurate distribution of chromosomes to daughter cells:

  1. Prophase: During this phase, chromosomes condense and become visible under a microscope, and the nuclear envelope begins to break down. The mitotic spindle, which is crucial for chromosome movement, starts to form from the centrosomes.
  1. Metaphase: In this phase, the chromosomes align along the metaphase plate (the cell's equatorial plane). This alignment ensures that each daughter cell will receive an identical set of chromosomes.

  2. Anaphase: During anaphase, the sister chromatids are pulled apart and move towards opposite poles of the cell. This separation is essential for ensuring that each new cell has the correct number of chromosomes.

  3. Telophase: In the final phase of mitosis, the separated chromatids reach the poles, and the nuclear envelope reforms around each set of chromosomes, leading to the re-establishment of two distinct nuclei within the cell.

Following these stages, cytokinesis occurs, which divides the cytoplasm and completes the process of cell division.
