Answer: (C)

Verified step by step guidance

1. Understand the process of mitosis, which is the division of a single cell into two genetically identical daughter cells. Mitosis consists of several phases: prophase, metaphase, anaphase, and telophase.
2. Recall that sister chromatids are identical copies of a chromosome connected by a centromere. During mitosis, these chromatids must be separated to ensure each daughter cell receives an identical set of chromosomes.
3. Identify the role of each phase in mitosis: Prophase involves the condensation of chromatin into visible chromosomes and the formation of the mitotic spindle. Metaphase is characterized by the alignment of chromosomes along the metaphase plate.
4. Focus on anaphase, where the separation of sister chromatids occurs. During anaphase, the centromeres split, and the spindle fibers pull the sister chromatids apart toward opposite poles of the cell, transforming them into individual daughter chromosomes.
5. Recognize that telophase is the final phase of mitosis, where the chromosomes arrive at the poles, de-condense, and are enclosed by a new nuclear envelope, completing the process of cell division.
