Detailed explanation-1: -During telophase, the newly separated chromosomes reach the mitotic spindle and a nuclear membrane forms around each set of chromosomes, thus creating two separate nuclei inside the same cell.

Detailed explanation-2: -During mitosis, each duplicated chromosome is evenly divided. Thus, during telophase two identical nuclei are created.

Detailed explanation-3: -Hence, the cell at telophase has two nuclei.

Detailed explanation-4: -During telophase I, the chromosomes are enclosed in nuclei. The cell now undergoes a process called cytokinesis that divides the cytoplasm of the original cell into two daughter cells.
