Answer:
Student C.
Explanation:
The student C statement is correct about the disappearing of Saturn's rings. The main reason of disappearing of Saturn's rings is the sloping of the Saturn planet. Saturn has its own orbit in which he revolve around the sun, During its movement, the orbit takes it to a location where the planet seems to tip just enough so that the rings slowly seem to be disappearing. The view of student A is incorrect because the ring is not made of methane gas, it is made of large pieces of comets, asteroids or shattered moons. The view of Student B is also incorrect because there is not just the ice coated dust particle but also pieces of rocks which reflect the light not refracted.
