Which of the following planets is listed as having rings along with Jupiter, Saturn, and Uranus?

• A. Jupiter
• B. Saturn
• C. Neptune
• D. Mars

Answer: (C)

Rings form from material orbiting a planet, and not all planets have them. Jupiter, Saturn, and Uranus are known for their rings, and Neptune also has a ring system, though it’s faint compared with Saturn’s. The existence of Neptune’s rings was confirmed by spacecraft and telescopic observations, showing that it joins the group of planets with rings. Mars does not have rings. So Neptune is the planet that completes the set of planets listed as having rings.
