Answer:
Option D
Explanation:
Jupiter is made almost totally from hydrogen and some hydrogen compounds. It may have a solid hydrogen core, then a liquid hydrogen layer, then a gaseous layer.
It is not known if Jupiter has a solid surface, or even a liquid surface. We measure Jupiter's diameter from the top of its gas layer.
The core is often described as rocky, but its detailed composition is unknown, as are the properties of materials at the temperatures and pressures.
The presence of a core during at least part of Jupiter's history is suggested by models of planetary formation that require the formation of a rocky or icy core massive enough to collect its bulk of hydrogen and helium from the protosolar nebula. Assuming it did exist, it may have shrunk as convection currents of hot liquid metallic hydrogen mixed with the molten core and carried its contents to higher levels in the planetary interior. A core may now be entirely absent, as gravitational measurements are not yet precise enough to rule that possibility out entirely.

In an attempt to reduce our dependence on non-renewable resources, and cut down on the harm to the environment, we could burn biomass to produce electricity.
