Match the following.
`{:("Column I","Column II"),((1)Mg^(2+),,"(i) Chlorophyll"),("(2) P",(ii) ATP),((3) Zn,"(iii) Alcohol dehydrogenase"),((4) Mo,"(iv) Nitrogenase"):}`

Options

A. (1)–(ii) ,(2)–(i),(3) –(iii), (4)– (iv)
B. (1)–(i) ,(2)–(ii) ,(3) –(iii), (4) – (iv)
C. (1)– (iv) , (2)–(i) ,(3) –(ii), (4)–(iii)
D. (1)– (iv) ,(2)–(iii) , (3) – (ii), (4)– (i)

Answer

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

### Step-by-Step Solution:

1. **Identify the first element in Column I: Mg²⁺ (Magnesium)**
- Magnesium is a crucial macronutrient for plants and is a central component of chlorophyll, which is essential for photosynthesis.
- **Match:** (1) Mg²⁺ → (i) Chlorophyll

2. **Identify the second element in Column I: P (Phosphorus)**
- Phosphorus is an essential element that is a key component of ATP (adenosine triphosphate), which is the energy currency of the cell.
- **Match:** (2) P → (ii) ATP

3. **Identify the third element in Column I: Zn (Zinc)**
- Zinc is a micronutrient that acts as a cofactor for various enzymes, including alcohol dehydrogenase, which is involved in the metabolism of alcohol.
- **Match:** (3) Zn → (iii) Alcohol dehydrogenase

4. **Identify the fourth element in Column I: Mo (Molybdenum)**
- Molybdenum is a trace element that is a component of the enzyme nitrogenase, which is involved in the nitrogen fixation process.
- **Match:** (4) Mo → (iv) Nitrogenase

### Final Matches:
- (1) Mg²⁺ → (i) Chlorophyll
- (2) P → (ii) ATP
- (3) Zn → (iii) Alcohol dehydrogenase
- (4) Mo → (iv) Nitrogenase

### Summary of Matches:
- (1) → (i)
- (2) → (ii)
- (3) → (iii)
- (4) → (iv)
