What happens during Telophase?
A
Nucleolus is visible
B
Spindle fibers break apart
C
Nuclear envelope forms
D
Chromosomes spread into chromatids
E
The cell starts to grow
Explanation: 

Detailed explanation-1: -During telophase, the chromosomes continue to decondense, the spindle disintegrates, and the nuclear membranes and nucleoli re-form. Telophase begins as anaphase comes to an end. During anaphase, the chromosomes or chromatids on the metaphase plate are split and driven towards opposing poles.

Detailed explanation-2: -Telophase is technically the final stage of mitosis. Its name derives from the latin word telos which means end. During this phase, the sister chromatids reach opposite poles. The small nuclear vesicles in the cell begin to re-form around the group of chromosomes at each end.

Detailed explanation-3: -During telophase both sets of chromatids are surround by new nuclear membranes and chromosomes decondense into chromatin.

Detailed explanation-4: -Mitosis ends with telophase, or the stage at which the chromosomes reach the poles. The nuclear membrane then reforms, and the chromosomes begin to decondense into their interphase conformations. Telophase is followed by cytokinesis, or the division of the cytoplasm into two daughter cells.

Detailed explanation-5: -Telophase begins when the decondensing daughter chromatids arrive at the poles, the kinetochore microtubules disappear, and the nuclear envelope reforms around the decondensing chromosomes to form the two daughter nuclei (Benavente, 1991).
