Match the following:
`{:("Column I","Column II"),(1."Boron",i."Solute transport"),(2."Permease",ii."Cytochromes"),(3.Mn,iii."Transmembrane proteins"),(4."iron",iv."photolysis of water"):}`

Options

A. 1-I,2-iii,3-iv,4-ii
B. 1-ii,2-iv,3-I,4-iii
C. 1-I,2-iv,3-ii,4-iii
D. 1-I,2-ii,3-iii,4-iv

Answer

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

### Step-by-Step Solution:

1. **Identify Boron**:
- Boron is known to play a crucial role in the transport of solutes in plants. It helps in the movement of nutrients and water across plant tissues.
- **Match**: Boron → Solute transport (1 → i)

2. **Identify Permease**:
- Permease is an enzyme that facilitates the transport of molecules across cell membranes. It is classified as a transmembrane protein because it spans the membrane.
- **Match**: Permease → Transmembrane proteins (2 → iii)

3. **Identify Manganese (Mn)**:
- Manganese acts as a cofactor in various biochemical reactions, particularly in the photolysis of water, which is the process of splitting water molecules during photosynthesis.
- **Match**: Manganese → Photolysis of water (3 → iv)

4. **Identify Iron**:
- Iron is an essential component of cytochromes, which are proteins involved in electron transport and redox reactions in cells. Iron acts as a cofactor within these proteins.
- **Match**: Iron → Cytochromes (4 → ii)

### Final Matches:
- 1 → i (Boron → Solute transport)
- 2 → iii (Permease → Transmembrane proteins)
- 3 → iv (Manganese → Photolysis of water)
- 4 → ii (Iron → Cytochromes)

### Conclusion:
The correct matching is:
1. Boron - Solute transport
2. Permease - Transmembrane proteins
3. Manganese - Photolysis of water
4. Iron - Cytochromes

Thus, the answer is the first option.
