Column - I and Column - II contains four emtries each. Entries of Column -I are to be matched with some entries of Column - II .
One or more than one entries of Column -I may have the matching with the same entries of Column - II.
`{:("column-I","column-II"),("(A) solid dispersed in solid","(P) solid foam "),("(B) Gas dispersed in solid ",(Q) " Aerosol"),("(C) solid dispersed in liquid ","(R) Solid sol "),("(D) solid dispersed in gas ","(S) sol "):}`

Options

A. `{:(A,B,C,D,),(R,P,S,Q,):}`
B. `{:(A,B,C,D,),(P,Q,R,S,):}`
C. `{:(A,B,C,D,),(S,R,Q,P,):}`
D. `{:(A,B,C,D,),(Q,R,P,S,):}`

Answer

To solve the problem of matching the entries from Column-I with those from Column-II, we will analyze each entry in Column-I and find the corresponding matches in Column-II based on the classification of colloids.

### Step-by-Step Solution:

1. **Identify the entries in Column-I:**
- (A) Solid dispersed in solid
- (B) Gas dispersed in solid
- (C) Solid dispersed in liquid
- (D) Solid dispersed in gas

2. **Identify the entries in Column-II:**
- (P) Solid foam
- (Q) Aerosol
- (R) Solid sol
- (S) Sol

3. **Match each entry from Column-I with Column-II:**
- **(A) Solid dispersed in solid:**
- This corresponds to (R) Solid sol.
- **Match:** (A) → (R)

- **(B) Gas dispersed in solid:**
- This corresponds to (P) Solid foam.
- **Match:** (B) → (P)

- **(C) Solid dispersed in liquid:**
- This corresponds to (S) Sol.
- **Match:** (C) → (S)

- **(D) Solid dispersed in gas:**
- This corresponds to (Q) Aerosol.
- **Match:** (D) → (Q)

4. **Summarize the matches:**
- (A) → (R)
- (B) → (P)
- (C) → (S)
- (D) → (Q)

### Final Matching:
- (A) Solid dispersed in solid → (R) Solid sol
- (B) Gas dispersed in solid → (P) Solid foam
- (C) Solid dispersed in liquid → (S) Sol
- (D) Solid dispersed in gas → (Q) Aerosol
