1. Jupiter - Largest planet with 12 satellites: Incorrect. Jupiter is indeed the largest planet, but it has more than 12 satellites. As of current knowledge, it has 79 known moons.
2. Uranus - Orbits the sun in a clockwise direction from east to west: Correct. Uranus is unique among the planets as it rotates on its side with its axis nearly parallel to the orbital plane, and it orbits the sun in a clockwise direction from east to west.
3. Venus - Twice the distance from the sun compared to Earth: Incorrect. Venus is actually closer to the sun than Earth. It is the second planet from the sun, whereas Earth is the third.
4. Neptune - Outermost planet visible with telescopes: Correct. Neptune is the outermost planet in the solar system and can be observed with the help of telescopes. Pluto was once considered the outermost planet but has been reclassified as a dwarf planet.
Hence, pairs 2 and 4 are correctly matched.

Analysis of the Pairs
To determine how many pairs are correctly matched, let's evaluate each one based on astronomical facts.
1. Jupiter - Largest planet with 12 satellites
- Fact Check: Jupiter is indeed the largest planet in our solar system. However, as of current knowledge, it has 79 known moons (satellites), not just 12.
- Conclusion: Incorrectly matched.
2. Uranus - Orbits the sun in a clockwise direction from east to west
- Fact Check: Uranus is unique among the planets as it rotates on its side, causing it to have a retrograde rotation, which means it does spin clockwise when viewed from above the North Pole.
- Conclusion: Correctly matched.
3. Venus - Twice the distance from the sun compared to Earth
- Fact Check: Venus is actually closer to the Sun than Earth. The average distance from the Sun to Venus is about 0.72 AU (astronomical units), while Earth is 1 AU away.
- Conclusion: Incorrectly matched.
4. Neptune - Outermost planet visible with telescopes
- Fact Check: Neptune is indeed the outermost planet in our solar system, but it is not typically visible with the naked eye and requires telescopes for observation. The outermost planet visible is actually Uranus.
- Conclusion: Incorrectly matched.
Final Assessment
- Correctly Matched Pairs: Only one pair is correctly matched (Uranus).
- Total Correct Matches: Thus, the correct answer is option 'B' - Only two pairs.
This conclusion reflects an understanding of the accurate details regarding the planets in our solar system.
