Metaphase includes attachment of chromatids to mitotic spindle and alignment of chromatids on the equatorial plate. Anaphase is marked by the division of centromere and movement of sister chromatids towards the opposite poles. Telophase is marked by the presence of daughter chromatids at the opposite poles. Prophase is marked by the appearance of chromosomes with sister chromatids due to condensation of the chromatin fibre. Thus, the correct answer is option A.
