Answer» The correct choice is (C) A decrease in the number of sets of chromosomes To elaborate: Decrease in the number of sets of chromosomes is not known as polyploidy. In polyploidy conditions, after the telophase stage of cell division, cytokinesis FAILS to occur which results in an INCREASE in a WHOLE set of chromosomes in an organism.
