Mitosis is the act of division between two cells, so if it's interrupted the cell does not divide to form two cells. Let's go through the choices: A is incorrect because if mitosis stops, the dividing stops. C is incorrect because in order for cytokinesis to occur, mitosis must happen. D is incorrect because the cell isn't growing during mitosis. The only one that fits is B, as the chromosomes cannot separate into two nuclei if mitosis stops.
