Match the column I and column II
`{:("column-I","Column-II"),(1.Zn,i."Sickle leaf of cocoa"),(2.Cu,ii."Exanthema"),(3.Mo,iii."Scald of beans"),(4.Mn,iv."Marsh spot disease"):}`

Options

A. 1-vi,2-iii,3-ii,4-i
B. 1-I,2-ii,3-iii,4-iv
C. 1-iv,2-iii,3-I,4-ii
D. 1-I,2-iv,3-ii,4-iii

Answer

To solve the matching question between Column I and Column II, we will identify the nutrient deficiencies associated with each disease listed in Column II.

### Step-by-Step Solution:

1. **Identify the first item in Column I: Zn (Zinc)**
- The disease associated with Zinc deficiency is "Sickle leaf of cocoa."
- **Match:** 1 → i

2. **Identify the second item in Column I: Cu (Copper)**
- The disease associated with Copper deficiency is "Exanthema."
- **Match:** 2 → ii

3. **Identify the third item in Column I: Mo (Molybdenum)**
- The disease associated with Molybdenum deficiency is "Scald of beans."
- **Match:** 3 → iii

4. **Identify the fourth item in Column I: Mn (Manganese)**
- The disease associated with Manganese deficiency is "Marsh spot disease."
- **Match:** 4 → iv

### Final Matches:
- 1 → i (Zn → Sickle leaf of cocoa)
- 2 → ii (Cu → Exanthema)
- 3 → iii (Mo → Scald of beans)
- 4 → iv (Mn → Marsh spot disease)
