Mercury has a large impact crater, the Caloris Basin, opposite which shock waves traveling through the planet created a region called the "jumbled terrain." Callisto has a large impact crater, Valhalla. What does the surface of Callisto look like on the opposite side from Valhalla?
A) The surface is jumbled, like that on Mercury.
B) There is no jumbled terrain because the distance through Callisto is too great for a shock wave to travel.
C) The opposite side of Callisto has been cratered more recently, so it is not possible to determine if a jumbled terrain was formed opposite Valhalla.
D) There is no jumbled terrain because Callisto's partially liquid interior damped out the shock waves.

Unlike Mercury, Callisto's partially liquid interior absorbed the shock waves from the impact that created Valhalla, preventing the formation of a jumbled terrain on the opposite side.
