(ii) Manganese - Splitting of water during photosynthesis
(iii) Zinc - Activates carboxylases
(iv) Copper - Involved in redox reactions
Which of these are correct

Options

A. (i), (ii) & (iii)
B. (ii), (iii) & (iv)
C. (i), (iii) & (iv)
D. All are correct

Answer

To determine which of the matches are correct, we will analyze each mineral and its associated function step by step.

### Step 1: Analyze Boron
- **Match**: Boron - Pollen germination
- **Explanation**: Boron is essential for the growth of pollen tubes and plays a crucial role in pollen germination. It helps in the structural integrity of cell walls and is involved in the transport of sugars.
- **Conclusion**: This match is **correct**.

### Step 2: Analyze Manganese
- **Match**: Manganese - Splitting of water during photosynthesis
- **Explanation**: Manganese is a vital component of the oxygen-evolving complex in photosystem II of photosynthesis. It participates in the splitting of water molecules, which is essential for the release of oxygen.
- **Conclusion**: This match is **correct**.

### Step 3: Analyze Zinc
- **Match**: Zinc - Activates carboxylases
- **Explanation**: Zinc is known to activate several enzymes, including carboxylases, which are important in various metabolic pathways, including photosynthesis and respiration.
- **Conclusion**: This match is **correct**.

### Step 4: Analyze Copper
- **Match**: Copper - Involved in redox reactions
- **Explanation**: Copper plays a critical role in redox reactions as it is a component of various enzymes, including cytochrome c oxidase, which is involved in cellular respiration.
- **Conclusion**: This match is **correct**.

### Final Conclusion
All four matches are correct:
1. Boron - Pollen germination: **Correct**
2. Manganese - Splitting of water during photosynthesis: **Correct**
3. Zinc - Activates carboxylases: **Correct**
4. Copper - Involved in redox reactions: **Correct**

Thus, the answer is that all the matches are correct.
