The correct option is B 1→4→5→3→2
∙ Mitotic cell division starts with the condensing of chromosome accompanied by splitting of the centrosome and its movement towards the opposite poles.
∙ As the nuclear envelope and nucleolus disappear, spindle fibres arise from the centrosomes and start binding to the condensed chromosomes at the centromeres.
∙ The chromosomes bound by the spindle fibers are then arranged in the middle of the cell forming the equatorial metaphase plate.
∙ Next the centromere splits and the sister chromatids are pulled away towards the poles by the contraction of spindle fibres.
∙ Following this, a cleavage furrow starts to develop in the middle of the cell while the nuclear membrane starts to reappear around the separated chromatids.
∙ The condensed chromatids start thinning into chromatin fibre along with reappearance of the nucleolus and the cleavage furrow deepening further.
∙ Finally as the nuclear membrane becomes fully intact, the cleavage furrow deepens and split the cells from middle into two daughter cells.
