What Is the Relationship Between Io and the Aurorae in Jupiter's

What is the relationship between Io and the aurorae in Jupiter's atmosphere?

A) Io blocks the motion of charged particles in Jupiter's magnetosphere, creating a shadow, or dark spot, in Jupiter's aurorae.
B) Io's gravitational pull raises tides in Jupiter's atmosphere, and the atmosphere emits light (aurorae) as it rises and falls through Jupiter's strong magnetic field.
C) The motion of Jupiter's magnetic field past Io generates electric currents between Io and Jupiter, which create aurorae at specific locations near Jupiter's magnetic poles.
D) Sulfurous solid particles ejected from Io's volcanoes fall into Jupiter's atmosphere, where they are ionized and emit light.
