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

Answer

To solve the problem of matching Column I with Column II, we will analyze each item in Column I and find its corresponding match in Column II based on their definitions and properties.

### Step-by-Step Solution:

1. **Identify Borax-bead (A)**:
- Borax, when heated, forms metaborate. The borax bead test is used to identify certain metal ions. Therefore, the correct match for Borax-bead is:
- **(A) Borax-bead → (iii) Metaborate**

2. **Identify Inorganic Benzene (B)**:
- Inorganic benzene is commonly referred to as borazine. It has similar structural and electronic properties to benzene, which is why it is called inorganic benzene. Thus, the correct match for Inorganic Benzene is:
- **(B) Inorganic Benzene → (iv) Borazine**

3. **Identify Antiseptic (C)**:
- Antiseptics are substances that prevent the growth of disease-causing microorganisms. Alum is often used as an antiseptic due to its astringent properties. Therefore, the correct match for Antiseptic is:
- **(C) Antiseptic → (i) Alum**

4. **Identify Bridged Hydrogens (D)**:
- Bridged hydrogens refer to the unique bonding in diborane (B2H6), where hydrogen atoms are shared between boron atoms in a three-centered two-electron bond. Hence, the correct match for Bridged Hydrogens is:
- **(D) Bridged Hydrogens → (ii) Diborane**

### Final Matches:
- (A) Borax-bead → (iii) Metaborate
- (B) Inorganic Benzene → (iv) Borazine
- (C) Antiseptic → (i) Alum
- (D) Bridged Hydrogens → (ii) Diborane

### Answer:
The correct option is:
- A → iii
- B → iv
- C → i
- D → ii
