Match of following columns
`{:("","Column-I","",Column-II),(A,"0.2-2.00mm",1,"silt"),(B,"less than 0.002 mm",2,"clay"),(C,"0.02-2 mm",3,"coarse sand particle"),(D,"0.002-0.02 mm",4,"fine sand particle"):}`

Options

A. `{:(A,B,C,D),(2,3,4,1):}`
B. `{:(A,B,C,D),(4,1,3,2):}`
C. `{:(A,B,C,D),(3,2,4,1):}`
D. `{:(A,B,C,D),(3,1,2,4):}`

Answer

To solve the matching question, we need to correctly pair the particle size ranges from Column-I with the corresponding soil types in Column-II. Here’s a step-by-step breakdown of the solution:

### Step 1: Identify the particle size ranges and their corresponding soil types
- **A: 0.2-2.00 mm**
- **B: less than 0.002 mm**
- **C: 0.02-0.2 mm**
- **D: 0.002-0.02 mm**

### Step 2: Match the sizes with soil types
1. **For A (0.2-2.00 mm)**: This range corresponds to **coarse sand**. So, we match A with 3.

2. **For B (less than 0.002 mm)**: This size is characteristic of **clay**. Therefore, we match B with 2.

3. **For C (0.02-0.2 mm)**: This range is identified as **fine sand**. Hence, we match C with 4.

4. **For D (0.002-0.02 mm)**: This size corresponds to **silt**. Thus, we match D with 1.

### Step 3: Summarize the matches
- A → 3 (coarse sand)
- B → 2 (clay)
- C → 4 (fine sand)
- D → 1 (silt)

### Final Answer
The correct matches are:
- A3
- B2
- C4
- D1
