Saturn is classified as a gas giant.
Saturn is an outer Jovian planet composed primarily of hydrogen and helium gases with no solid planetary surface, which defines it as a gas giant.

Step-by-Step Solution

1
Classify the planets of the solar system based on composition and structural characteristics.
The inner four planets (Mercury, Venus, Earth, Mars) are terrestrial rocky planets, while the outer planets are Jovian giant planets.
Planets located inside the asteroid belt are composed primarily of silicates and metals, whereas outer planets are fluid-dominated giants.
2
Differentiate between the options provided to find the gas giant.
Saturn consists predominantly of hydrogen and helium without a well-defined solid surface, placing it firmly in the gas giant category.
Among the options, only Saturn belongs to the Jovian gas giant family.
