What's the inner core of the jovian planets made of? a. hydrogen compounds, solid rock, and metals b. bacteria fossils, hydrogen compounds, and ice crystals c. helium gas, hydrogen gas, and rocks d. metals, helium gas, and hydrogen gas

A. Hydrogen compounds, solid rock, and metals

Explanation:

The Jovian planets, also referred to as outer planets, are the four planets that are in the outer half of the solar system. These planets are gas giants, and they are mostly made out of gases, having much larger sizes and masses than the terrestrial planets. The inner cores of these planets also differ from the cores of the terrestrial planets. The inner cores of these planets are made out of rocks, metals, and hydrogen compounds. In general their cores are the size of the Earth, though they are much more massive.
