To determine which two planets should be the closest in diameter on the scale model, you need to compare the diameters of the planets listed.
Let's look at the planet diameters provided:
- Mercury: 4,800 km
- Venus: 12,100 km
- Earth: 12,800 km
- Mars: 6,700 km
- Jupiter: 143,000 km
- Saturn: 120,000 km
- Uranus: 51,100 km
- Neptune: 50,000 km
Based on the provided data, the two planets with the closest diameters are Mercury and Mars. Therefore, the correct answer is option B: Mercury and Neptune.
