Which term refers to the outer planets in the solar system, including Jupiter, Saturn, Uranus, and Neptune?

• A. Planets farthest from the Sun
• B. Venus
• C. Geocentric model
• D. Ocean Basin

Answer: (A)

The idea being tested is grouping planets by their distance from the Sun. The outer planets are those that lie farther from the Sun than the rocky, inner planets, and they include Jupiter, Saturn, Uranus, and Neptune. The term that fits this idea is “planets farthest from the Sun,” because it describes exactly which planets are in that outer, distant group. The other options don’t describe this set: Venus is an inner planet, the geocentric model is a theory about the universe’s structure, and an ocean basin is a geographical feature on Earth.
