D. A-III, B-II, C-I, D-IV
Step-by-step solution
According to NCERT, the hallmark events of the mitotic phases are as follows: Prophase is marked by the initiation of condensation of chromosomal material (A-III). Metaphase is characterized by the alignment of chromosomes at the equator, forming the metaphase plate (B-II). Anaphase is defined by the simultaneous splitting of centromeres and the separation of sister chromatids, which then migrate to opposite poles (C-I). Telophase is the final stage where chromosomes decondense and lose their individuality, and org
