What typically characterizes a gas giant planet?

A gas giant planet is typically characterized by its large size and gaseous composition. Unlike terrestrial planets, which have solid surfaces and are smaller in size, gas giants are predominantly made up of hydrogen and helium, with thick atmospheres and minimal solid surfaces. Their immense gravitational pull allows them to hold onto these gases, resulting in their characteristic size. This gaseous composition contributes to features such as extensive atmospheres, high winds, and prominent storm systems, like the Great Red Spot on Jupiter.

The other options describe characteristics that are not representative of gas giants; for example, small size and solid cores, high density and rocky surfaces, as well as minimal atmospheres and icy rings are more typical of terrestrial planets or other celestial bodies. Thus, the selection of large size and gaseous composition accurately reflects the nature of gas giants.
