Which of These Conclusions Is Correct on the Basis of Observations

Multiple Choice

Which of these conclusions is correct on the basis of observations of the motions of Jupiter's clouds?

A) The planet rotates differentially, with the equatorial regions rotating fastest while intermediate latitudes and polar regions rotate more slowly.
B) Intermediate-latitude regions rotate fastest while equatorial and polar regions rotate more slowly, as shown by the presence of bands and zones and locally rotating spots and ovals.
C) The planet rotates as a solid body because of its great mass and self-gravitation, with all regions having the same rotation speed.
D) The planet rotates differentially, with equatorial regions rotating slowest and rotation speed increasing toward both poles.
