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 need to identify the correct associations based on the deficiencies of certain minerals and the diseases or conditions they cause in plants. Here’s a step-by-step solution:

### Step 1: Identify the Condition for Zinc (Zn)
- **Condition**: Sickle leaf of cocoa
- **Explanation**: Sickle leaf is associated with chlorosis, which occurs due to a deficiency of zinc.
- **Match**: 1 (Zn) → i ("Sickle leaf of cocoa")

### Step 2: Identify the Condition for Copper (Cu)
- **Condition**: Exanthema
- **Explanation**: Exanthema is characterized by gum exudation from the bark of trees, which is a symptom of copper deficiency.
- **Match**: 2 (Cu) → ii ("Exanthema")

### Step 3: Identify the Condition for Molybdenum (Mo)
- **Condition**: Scald of beans
- **Explanation**: Scald of beans, also referred to as sunburn, is caused by a deficiency of molybdenum.
- **Match**: 3 (Mo) → iii ("Scald of beans")

### Step 4: Identify the Condition for Manganese (Mn)
- **Condition**: Marsh spot disease
- **Explanation**: Marsh spot disease is characterized by black spots in pea plants and is linked to manganese deficiency.
- **Match**: 4 (Mn) → iv ("Marsh spot disease")

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

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