The Cassini division in Saturn's rings is


(a)   a gap in the rings, swept clear of debris by gravitational disturbance from Mimas, a satellite which orbits well outside the rings with an orbital period one-half that of material in the gap.
(b)   a gap in the rings, swept clear of debris by a small moon orbiting within the gap.
(c)   the boundary between the B ring and the C ring, where the density and brightness of the rings change suddenly.
