The Distribution of Mass Inside the Planet Saturn Is Believed

The distribution of mass inside the planet Saturn is believed to be concentrated more centrally than it is in Jupiter. The most important observation supporting this conclusion is that Saturn:

A) is more massive than Jupiter and is more gravitationally compressed at its center.
B) has a significantly lower density than has Jupiter.
C) is less oblate (flattened) than Jupiter, even though it rotates at approximately the same speed.
D) is more oblate (flattened) then Jupiter, even though it rotates more slowly.
