Options

A. (A) `to` (iv), (B) `to` (iii), (C ) `to` (ii), (D) `to` (i)
B. (A) `to` (iv), (B) `to` (i), (C ) `to` (iii), (D) `to` (ii)
C. (A) `to` (iii), (B) `to` (ii), (C ) `to` (i), (D ) `to` (iv)
D. (A) `to` (ii), (B) `to` (iii), (C ) `to` (iv) , (D) `to` (i)

Answer

To solve the matching question between Column I and Column II, we will analyze each item in Column I and find the corresponding item in Column II.

### Step-by-Step Solution:

1. **Identify the first item in Column I: "Used as lubricant" (A)**
- The correct match is **(ii) Graphite**. Graphite is known for its slippery texture due to the weak Van der Waals forces between its layers, making it an effective lubricant.

2. **Identify the second item in Column I: "Oxide with three-dimensional structure" (B)**
- The correct match is **(iii) Silica**. Silica (SiO2) has a three-dimensional tetrahedral structure where each silicon atom is bonded to four oxygen atoms, forming a network solid.

3. **Identify the third item in Column I: "Used in solar cells" (C)**
- The correct match is **(iv) Silicon**. Silicon is a semiconductor widely used in solar cells to convert sunlight into electricity.

4. **Identify the fourth item in Column I: "Anhydride of carbonic acid" (D)**
- The correct match is **(i) Carbon dioxide**. Carbon dioxide (CO2) is the anhydride of carbonic acid (H2CO3), as it forms carbonic acid when dissolved in water.

### Final Matches:
- A → (ii) Graphite
- B → (iii) Silica
- C → (iv) Silicon
- D → (i) Carbon dioxide

### Conclusion:
The correct matches are:
- A - (ii)
- B - (iii)
- C - (iv)
- D - (i)

Thus, the final answer is option 4.
