Match column I with column II and select the correct option from the codes given below
`{:(underset("(Activator element) ")("Column I"),underset("(Enzyme)")("Column II")),(A" "Mg^(2+) ,,(i)" Nitrate reductase"),(B." "Zn^(2+),(ii)." RuBisCO, PEPCase"),(C." "Mo,(iii)." Alcohol dehydrogenase"):}`

Options

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

Answer

To solve the matching question, we need to correctly pair the activator elements from Column I with their respective enzymes from Column II. Let's go through each activator element one by one.

### Step-by-Step Solution:

1. **Identify the first activator element:**
- **Activator Element:** Mg²⁺ (Magnesium)
- **Enzyme:** Nitrate reductase
- **Match:** A (Mg²⁺) → (i) Nitrate reductase

2. **Identify the second activator element:**
- **Activator Element:** Zn²⁺ (Zinc)
- **Enzyme:** Alcohol dehydrogenase
- **Match:** B (Zn²⁺) → (iii) Alcohol dehydrogenase

3. **Identify the third activator element:**
- **Activator Element:** Mo (Molybdenum)
- **Enzyme:** RuBisCO and PEPCase
- **Match:** C (Mo) → (ii) RuBisCO, PEPCase

4. **Compile the matches:**
- A → (i)
- B → (iii)
- C → (ii)

5. **Final Matching:**
- A (Mg²⁺) → (i) Nitrate reductase
- B (Zn²⁺) → (iii) Alcohol dehydrogenase
- C (Mo) → (ii) RuBisCO, PEPCase

6. **Select the correct option:**
- Based on the matches, the correct option is option number 3.

### Final Answer:
The correct matches are:
- A → (i)
- B → (iii)
- C → (ii)

Thus, the answer is **option number 3**.
