Answer:
B)Prophase,Metaphase,Anaphase,Telephase
Step-by-step explanation:
Prophase:At this stage,the chromatin threads condense to form distinct chromosomes, long and thin at first,later become shorter and fatter. Nucleolus disappears, nuclear membrane disintegrates, series of spindle (protein) fibres are formed spanning the cell from end to end.
Metaphase:Here, Chromosomes migrate to the central plain of the cells and arrange themselves round the equator of the spindle, attached by centromeres to be 'spindle fibres' microtubule.
Chromatids of each chromosome move slightly apart at the centromere regions,the sister chromatids being oriented towards opposite poles
Anaphase: Chromatids belonging to each chromosome part company and move towards opposite poles of the spindle, probably by a pull from the spindle fibres attached to the centromere which shortens.
Telephase: Chromatids reach the polar ends of the spindle and become densely packed together. Cell divide into two. Spindle fibres break down, centrioles replicate. Nuclear membrane is re-formed. Nucleolus reappears. Chromosomes gradually uncoil and return to their original thread-like form i.e, Chromatin threads.
