1. Mercury - Smallest and closest to the sun: This pair is correctly matched. Mercury is indeed the smallest planet in the solar system and the closest to the sun.
2. Jupiter - Second largest planet with 12 satellites: This pair is incorrectly matched. Jupiter is the largest planet in the solar system, not the second largest. It has more than 12 satellites; in fact, it has at least 79 known moons.
3. Uranus - Orbits around the sun in a clockwise direction from east to west: This pair is correctly matched. Uranus is unique in that it rotates on its side, and its rotation is from east to west, which is opposite to the direction of most of the other planets.
4. Neptune - Natural satellite is the moon: This pair is incorrectly matched. Neptune does not have the moon as its natural satellite. Neptune has 14 known moons, with Triton being the largest.
Thus, only pairs 1 and 3 are correctly matched.

Analysis of the Planetary Pairs
To determine how many pairs are correctly matched, let's evaluate each statement:
1. Mercury - Smallest and closest to the sun
- Mercury is indeed the smallest planet in our solar system and the closest to the sun.
- Correct Match: Yes
2. Jupiter - Second largest planet with 12 satellites
- Jupiter is the largest planet in our solar system, not the second largest. It has more than 79 known satellites, not just 12.
- Correct Match: No
3. Uranus - Orbits around the sun in a clockwise direction from east to west
- Uranus is unique among planets as it rotates on its side, leading to its retrograde rotation. It does indeed orbit the sun in a clockwise direction from east to west.
- Correct Match: Yes
4. Neptune - Natural satellite is the moon
- Neptune does have natural satellites, with Triton being the most notable. However, the statement incorrectly suggests that Neptune's natural satellite is "the moon," which is misleading as "the moon" typically refers to Earth's satellite.
- Correct Match: No
Conclusion
- Only the first and third pairs are correctly matched. Thus, the correct answer is Only two pairs.
The final count of correctly matched pairs is two, supporting the answer option 'B'.
