Match the columns nad choose the correct option
`{:("Column I", "Column II"),(A."Magnesium",i."Alcohol dehydrogenase"),(B."Molybdenum",ii."phosphoenol pyruvate"),(C."Zinc",iii."Nitrogenase"):}`

Options

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

Answer

To solve the matching question between Column I and Column II, we will analyze each element in Column I and identify its corresponding enzyme or function from Column II.

### Step-by-step Solution:

1. **Identify Magnesium:**
- Magnesium is known to be a crucial component of several enzymes, including phosphoenolpyruvate carboxylase.
- **Match:** Magnesium (A) → Phosphoenolpyruvate (ii).

2. **Identify Molybdenum:**
- Molybdenum is an essential element for the enzyme nitrogenase, which is involved in nitrogen fixation.
- **Match:** Molybdenum (B) → Nitrogenase (iii).

3. **Identify Zinc:**
- Zinc acts as an activator for various enzymes, including alcohol dehydrogenase.
- **Match:** Zinc (C) → Alcohol dehydrogenase (i).

### Final Matching:
- A (Magnesium) → ii (Phosphoenolpyruvate)
- B (Molybdenum) → iii (Nitrogenase)
- C (Zinc) → i (Alcohol dehydrogenase)

### Conclusion:
The correct matches are:
- A → ii
- B → iii
- C → i

Thus, the correct option based on the matches is **Option 1**.
