One significant physical characteristic of the high-pressure form of hydrogen that is thought to exist in the interior of Jupiter is that it
(a) is a crystalline solid, making up the core and interior of Jupiter.
(b) is dark red in color; it is this hydrogen that we are seeing through gaps between the clouds, in Jupiter's belts.
(c) is an electrically conducting liquid.
(d) remains gaseous all the way to the central, icy ocean, despite the immense pressure at these depths.
