B

To match List-I with List-II, we need to analyze each item in List-I and find its corresponding unit of measurement in List-II:

1. **Distance between earth and stars** - This is typically measured in light years, as stars are very far away. Therefore, it corresponds to item 3 in List-II.
2. **Inter-atomic distance in a solid** - This is usually on the order of Angstroms (10^-10 meters). Thus, it matches with item 2 in List-II.
3. **Size of the nucleus** - The size of atomic nuclei is typically measured in Fermis (1 Fermi = 10^-15 meters). Hence, it corresponds to item 4 in List-II.
4. **Wavelength of infrared laser** - Wavelengths in the infrared range are usually measured in microns (1 micron = 10^-6 meters). Therefore, it links with item 1 in List-II.

Now we can summarize our matches:
- A (Distance between earth and stars) - 3 (Light years)
- B (Inter-atomic distance in a solid) - 2 (Angstroms)
- C (Size of the nucleus) - 4 (Fermi)
- D (Wavelength of infrared laser) - 1 (Microns)

Thus, the corresponding codes from List-II are 3, 2, 4, 1. Therefore, the correct answer is Option B (3 2 4 1).
