The reason the rings of Saturn exist is because
A) the ring material lies within the Roche limit of Saturn.
B) the gravitational influence of Titan confines them to those orbits.
C) the eruptions of Mimas' volcanoes are keeping them supplied with ice.
D) there has not been sufficient time for the ring particles to form a moon.
E) Saturn's rapid rotation is spinning material away from its equator, out into space.
