B. `A-G, B-H, C-E, D-F`
C. `A-H, B-G, C-E, D-F`
D. `A-G, B-H, C-F, D-E`

Answer

To solve the matching question between List-I and List-II, we will analyze each item in List-I and find the corresponding item in List-II based on the contributions of each scientist or concept.

### Step-by-Step Solution:

1. **Identify Einstein's Contribution:**
- Einstein is known for his work on the photoelectric effect, which demonstrated the particle nature of light.
- **Match:** a) Einstein → h) particle nature of light

2. **Identify Huygens' Contribution:**
- Huygens is famous for his wave theory of light and the principle of wave fronts.
- **Match:** b) Huygens → g) wave nature of light

3. **Identify Foucault's Contribution:**
- Foucault is known for measuring the speed of light using a rotating mirror experiment.
- **Match:** c) Foucault → e) velocity of light

4. **Identify Fresnel's Contribution:**
- Fresnel contributed significantly to the understanding of diffraction and interference of light.
- **Match:** d) Fresnel → f) diffraction of light

### Final Matches:
- a) Einstein → h) particle nature of light
- b) Huygens → g) wave nature of light
- c) Foucault → e) velocity of light
- d) Fresnel → f) diffraction of light

### Summary of Matches:
- A → H
- B → G
- C → E
- D → F
