Answer

To solve the problem of matching the colloidal dispersions from List-I with their corresponding nature of dispersion from List-II, we will analyze each item step by step.

### Step-by-Step Solution:

1. **Identify the Colloidal Dispersion for A (Milk)**:
- Milk is an emulsion, which is a type of colloid.
- In milk, the disperse phase is liquid (fat globules) and the dispersion medium is also liquid (water).
- Therefore, milk matches with **(4) Liquid in Liquid**.

2. **Identify the Colloidal Dispersion for B (Clouds)**:
- Clouds are an example of an aerosol, which is another type of colloid.
- In clouds, the disperse phase is liquid (water droplets) and the dispersion medium is gas (air).
- Thus, clouds match with **(2) Liquid in Gas**.

3. **Identify the Colloidal Dispersion for C (Paints)**:
- Paints are classified as sols, which are colloidal systems.
- In paints, the disperse phase is solid (pigment particles) and the dispersion medium is liquid (solvent).
- Therefore, paints match with **(1) Solid in Liquid**.

4. **Identify the Colloidal Dispersion for D (Jellies)**:
- Jellies are also a type of colloid, specifically a gel.
- In jellies, the disperse phase is liquid (water) and the dispersion medium is solid (gel structure).
- Hence, jellies match with **(5) Liquid in Solid**.

### Final Matching:
- A (Milk) → (4) Liquid in Liquid
- B (Clouds) → (2) Liquid in Gas
- C (Paints) → (1) Solid in Liquid
- D (Jellies) → (5) Liquid in Solid

### Answer:
The correct matching is:
- A - 4
- B - 2
- C - 1
- D - 5
