Options

A. a-iii,b-ii,c-I,d-v
B. a-iii,b-iv,c-ii,d-i
C. a-v,b-ii,c-iii,d-iv
D. a-iv,b-I,c-iii,d-ii

Answer

To solve the matching question between Column I and Column II, we will analyze each item in Column I and identify the corresponding element from Column II based on their functions in plant nutrition.

### Step-by-Step Solution:

1. **Photolysis of Water**:
- Photolysis of water occurs during photosynthesis, where water is split to release oxygen.
- Manganese (Mn) plays a crucial role in this process as it is involved in the splitting of water molecules.
- **Match**: Photolysis of water (1) → Manganese (iii).

2. **Diazotrophy**:
- Diazotrophy refers to the biological fixation of nitrogen, which is essential for converting atmospheric nitrogen into a usable form for plants.
- Molybdenum (Mo) is a vital element for nitrogen-fixing bacteria and is essential for the enzyme nitrogenase.
- **Match**: Diazotrophy (2) → Molybdenum (iv).

3. **Cytochrome-C Oxidase**:
- Cytochrome-C oxidase is an enzyme involved in the electron transport chain and redox reactions.
- Copper (Cu) is a key component of this enzyme and is necessary for its function.
- **Match**: Cytochrome-C oxidase (3) → Copper (ii).

4. **Biosynthesis of IAA**:
- IAA (Indole-3-acetic acid) is a plant hormone involved in growth and development.
- Zinc (Zn) is essential for the synthesis of auxins, including IAA.
- **Match**: Biosynthesis of IAA (D) → Zinc (i).

### Final Matches:
- 1 → iii (Photolysis of water → Manganese)
- 2 → iv (Diazotrophy → Molybdenum)
- 3 → ii (Cytochrome-C oxidase → Copper)
- D → i (Biosynthesis of IAA → Zinc)

### Complete Answer:
- 1 → iii (Manganese)
- 2 → iv (Molybdenum)
- 3 → ii (Copper)
- D → i (Zinc)
