Match the following :
`{:((i),"Foam",(a),"smoke"),((ii),"Gel",(b),"cell fluid"),((iii),"Aerosol",(c),"jellies"),((iv),"Emulsion",(d),"rubber"),(,,(e),"froth"),(,,(f),"milk"):}`

Options

A. (i) - (d) , (ii) - (b) , (iii) - (a) , (iv) - (e)
B. (i) - (b) , (ii) - (c) , (iii) - (e) , (iv) - (d)
C. (i) - (e) , (ii) - (c) , (iii) - (a) , (iv) - (f)
D. (i) - (d) , (ii) - (b) , (iii) - (e) , (iv) - (f)

Answer

To solve the matching question, we need to identify the correct pairings between the types of colloids and their respective examples. Let’s analyze each type of colloid one by one.

### Step-by-step Solution:

1. **Identify Foam**:
- Foam is a colloid where gas is dispersed in a liquid.
- Example: Froth (e).
- **Match**: (i) Foam → (e) Froth.

2. **Identify Gel**:
- Gel is a colloid that has properties between solid and liquid. It consists of a liquid dispersed in a solid.
- Example: Jellies (c).
- **Match**: (ii) Gel → (c) Jellies.

3. **Identify Aerosol**:
- An aerosol is a colloid where solid particles are dispersed in a gas.
- Example: Smoke (a).
- **Match**: (iii) Aerosol → (a) Smoke.

4. **Identify Emulsion**:
- An emulsion is a colloid where liquid droplets are dispersed in another liquid.
- Example: Milk (f).
- **Match**: (iv) Emulsion → (f) Milk.

### Final Matching:
- (i) Foam → (e) Froth
- (ii) Gel → (c) Jellies
- (iii) Aerosol → (a) Smoke
- (iv) Emulsion → (f) Milk

Thus, the correct matches are:
- (i) → (e)
- (ii) → (c)
- (iii) → (a)
- (iv) → (f)
