Which scenario could explain how such a multinucleated cell might have come to be? (a) The cell underwent repeated mitosis with simultaneous cytokinesis. (b) The cell had multiple S phases before it entered mitosis. (c) The cell underwent repeated mitosis, but cytokinesis did not occur. (d) The cell underwent repeated cytokinesis but no mitosis. (e) The cell actually went through meiosis and not mitosis.
