Jupiter's Atmosphere Displays Spectacular Cyclonic and Anticyclonic Storms, Some Persisting

Jupiter's atmosphere displays spectacular cyclonic and anticyclonic storms, some persisting for long periods of time. How do these storms form?

A) Jupiter has a very strong magnetic field, and these storms both form the field and are strengthened by it as it feeds electric currents in the atmosphere.
B) They form like storms on the Sun, for low level nuclear fusion in Jupiter's core.
C) They are due to internal heat exchange within the planet, basically convection currents transferring internal heat to the surface.
D) Like on Earth, they result from differential solar heating of the equatorial region versus poles, and resultant atmospheric circulation.
