The correct option is (c).
Explanation
Planetary rings are disk-shaped regions of dust, rock, and ice particles orbiting a planet. While Saturn is most famous for its rings, ring systems are a characteristic feature of all the giant planets in the Solar System.
- Statement 1 is Incorrect: Planetary rings are not invisible from Earth. Specifically, Saturn's rings are highly reflective and extensive, making them clearly visible from Earth even with small telescopes. While the rings of Jupiter, Uranus, and Neptune are much fainter and darker, requiring powerful instruments to detect, the blanket statement that planetary rings are invisible even with powerful telescopes is factually wrong.
- Statement 2 is Correct: All four Jovian (gas giant) planets-Jupiter, Saturn, Uranus, and Neptune-possess ring systems. Text specifically highlights that Jupiter, Saturn, and Uranus have rings around them.
- Statement 3 is Correct: These rings are essentially belts of small debris. They are composed of billions of particles ranging in size from microscopic dust to large boulders, primarily made of water ice and rocky material.
Key Takeaway: All outer planets (Jupiter, Saturn, Uranus, and Neptune) have ring systems composed of debris, and Saturn's rings are distinctively visible from Earth through telescopes.
