The correct answer to this question is Telophase. This phase occurs in the eukaryotic cell. It happens during both mitosis and meiosis. It is the final stage of both of these cell cycles. Any effects of prometaphase and prophase are reversed during telophase. It is also the phase where sister chromatids reach opposite ends of the poles.
Telophase is a phase where many things happen such as the chromosomes uncoiling, which in turn forms chromatin, the spindle breaks down, and the preparation of genetic material occurs. This type of question would be found on a science test, related to cells.
