Answer: (A)

Verified step by step guidance

1. Understand the stages of mitosis: Mitosis is divided into several stages: prophase, metaphase, anaphase, and telophase.
2. Identify the key events in each stage: In prophase, chromosomes condense and become visible. In metaphase, chromosomes align at the cell's equatorial plate. In anaphase, sister chromatids are pulled apart to opposite poles of the cell. In telophase, the cell begins to divide, and nuclear membranes start to reform.
3. Focus on the event of chromatids being pulled apart: This specific event occurs when the sister chromatids, which are identical copies of a chromosome, are separated and moved to opposite ends of the cell.
4. Relate the event to the correct stage: The separation of sister chromatids is a defining characteristic of anaphase.
5. Conclude that the stage of mitosis where chromatids are pulled apart is anaphase, based on the description of events in each stage.
