Read the following matches
(i) Zinc - Activator of catalase
(ii) Calcium - Required during formation of mitotic spindle
(iii) Sulphur - Constituent of ferredoxin
(iv) Chlorine - Essential for water- splitting reaction in photosynthesis
Which of these are correct

Options

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

Explanation

To solve the question regarding the matches of minerals and their functions, we will analyze each option step by step.

### Step-by-Step Solution:

1. **Zinc - Activator of catalase**:
- Catalase is an enzyme that catalyzes the decomposition of hydrogen peroxide into water and oxygen. The primary metal ion that activates catalase is iron, not zinc. Therefore, this match is **incorrect**.

2. **Calcium - Required during formation of mitotic spindle**:
- Calcium plays a crucial role in various cellular processes, including cell division. It is indeed required for the formation of the mitotic spindle during mitosis. Thus, this match is **correct**.

3. **Sulphur - Constituent of ferredoxin**:
- Ferredoxin is a protein that contains iron and is involved in electron transfer in various biological processes. Sulphur is a component of some forms of ferredoxin, making this match **correct**.

4. **Chlorine - Essential for water-splitting reaction in photosynthesis**:
- Chlorine is involved in the process of photosynthesis, particularly in the light reactions where water is split (photolysis) to release oxygen. Therefore, this match is **correct**.

### Conclusion:
From the analysis:
- **Zinc** - Incorrect
- **Calcium** - Correct
- **Sulphur** - Correct
- **Chlorine** - Correct

Thus, the correct matches are **Calcium, Sulphur, and Chlorine**.

### Final Answer:
The correct matches are:
- (ii) Calcium - Required during formation of mitotic spindle
- (iii) Sulphur - Constituent of ferredoxin
- (iv) Chlorine - Essential for water-splitting reaction in photosynthesis
