Options

A. A-(i),B-(ii),C-(iii),D-(iv),E-(v)
B. A-(iv),B-(i),C-(iii),D-(ii),E-(v)
C. A-(iii),B-(ii),C-(iv),D-(v),E-(i)
D. A-(ii),B-(iii),C-(v),D-(i),E-(iv)

Answer

To solve the matching question regarding the elements and their associated functions, we will analyze each element and its role step by step.

### Step-by-Step Solution:

1. **Identify Boron (A)**:
- Boron is essential for pollen germination in plants. It is required in small amounts, and while it stimulates pollen germination, excessive concentrations can inhibit it.
- **Match**: (A) Boron → (iv) Pollen germination.

2. **Identify Manganese (B)**:
- Manganese plays a crucial role in photosynthesis, specifically in the photolysis of water, which is the splitting of water molecules to release oxygen.
- **Match**: (B) Manganese → (i) Splitting of H₂O to liberate O₂ during photosynthesis.

3. **Identify Molybdenum (C)**:
- Molybdenum is a key component of the enzyme nitrogenase, which is involved in nitrogen fixation.
- **Match**: (C) Molybdenum → (iii) Component of nitrogenase.

4. **Identify Zinc (D)**:
- Zinc is necessary for the synthesis of auxins, which are plant hormones that regulate growth.
- **Match**: (D) Zinc → (ii) Needed for synthesis of auxins.

5. **Identify Iron (E)**:
- Iron is a component of ferredoxin, which is involved in various metabolic processes including photosynthesis and nitrogen fixation.
- **Match**: (E) Iron → (v) Component of ferredoxin.

### Final Matches:
- (A) Boron → (iv) Pollen germination
- (B) Manganese → (i) Splitting of H₂O to liberate O₂ during photosynthesis
- (C) Molybdenum → (iii) Component of nitrogenase
- (D) Zinc → (ii) Needed for synthesis of auxins
- (E) Iron → (v) Component of ferredoxin
