The Magnetosphere of Jupiter Is

The magnetosphere of Jupiter is

A) a region of charged particles extending along the orbit of the satellite Io, forming a ring around Jupiter.
B) the magnetized hydrogen in the inner regions of Jupiter just outside the solid core, where the planet's magnetic field is produced.
C) a narrow layer in Jupiter's atmosphere, just above the cloud tops, in which intense electric currents flow and generate the planet's magnetic field.
D) a large space around Jupiter in which its magnetic field has excluded the solar wind but that is filled with high-energy charged particles.
