According to the textbook:

• Statement D is Correct: The key events of Telophase include the reformation of the nucleolus, Golgi complex, and ER .
• Statement A is Incorrect: Tetrads (bivalents) form during Zygotene (synapsis) and become clearly visible during Pachytene, not Leptotene .
• Statement B is Contextually Incorrect: While centromeres split during Anaphase of Mitosis and Anaphase II , they do not split during Anaphase I of meiosis (homologous chromosomes separate, but sister chromatids remain associated) . Given the other options refer to Meiosis, this statement is not universally true.
• Statement C is Incorrect: Terminalization of chiasmata occurs during Diakinesis, not Pachytene .
