(b) Telophase
Explanation:
Telophase is the final phase of mitosis where several reversal events occur to restore the nucleus to its interphase state. During telophase, the chromosomes reach the poles, uncoil, and become less distinct. The nuclear envelope forms again around each set of chromosomes, the nucleolus reappears, and the spindle fibers disassemble. This prepares the cell for the subsequent division of the cytoplasm (cytokinesis).
