B. A–(iii), B–(ii), C–(i)
C. A–(iii), B–(i), C–(ii)
D. None of the above

Answer

To solve the matching question, we need to identify the correct uses for each compound listed. Let's analyze each compound and its corresponding use step by step.

### Step 1: Identify the compounds and their uses
We have the following compounds and potential uses:
- **A. CHCl₃** (Chloroform)
- **B. CCl₄** (Carbon Tetrachloride)
- **C. CF₂Cl₂** (Dichlorodifluoromethane)

The uses provided are:
1. Refrigerant
2. Fire extinguisher
3. Anesthetic

### Step 2: Match CHCl₃ (Chloroform)
Chloroform (CHCl₃) is historically known to be used as an anesthetic. Although its use has decreased due to safety concerns, it was primarily used to induce anesthesia in patients. Therefore, we can match:
- **A. CHCl₃ → (iii) Anesthetic**

### Step 3: Match CCl₄ (Carbon Tetrachloride)
Carbon Tetrachloride (CCl₄) is commonly used as a fire extinguisher due to its effectiveness in suppressing flames. Thus, we can match:
- **B. CCl₄ → (ii) Fire extinguisher**

### Step 4: Match CF₂Cl₂ (Dichlorodifluoromethane)
Dichlorodifluoromethane (CF₂Cl₂) is a type of chlorofluorocarbon (CFC) and is primarily used as a refrigerant in refrigeration and air conditioning systems. Hence, we can match:
- **C. CF₂Cl₂ → (i) Refrigerant**

### Summary of Matches
Now, let's summarize the matches:
- **A. CHCl₃ → (iii) Anesthetic**
- **B. CCl₄ → (ii) Fire extinguisher**
- **C. CF₂Cl₂ → (i) Refrigerant**

### Final Answer
The correct answer is:
- **A → iii, B → ii, C → i**
