Match column A and B:
`{:("A - Minerals","B- plants"),(1.Si, i."Diatoms"),(2.Na,ii. "Halpohytes"),(3.CO,iii. "Microbes"),(4.AI, iv."Ferms"):}`

Options

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

Answer

To solve the matching problem between Column A (Minerals) and Column B (Plants), we will analyze each mineral and its corresponding plant type based on their known associations.

### Step-by-Step Solution:

1. **Identify the Minerals in Column A:**
- The minerals listed are:
1. Si (Silicon)
2. Na (Sodium)
3. Co (Cobalt)
4. Al (Aluminum)

2. **Identify the Plants in Column B:**
- The plants listed are:
i. Diatoms
ii. Halophytes
iii. Microbes
iv. Ferns

3. **Match Each Mineral with the Appropriate Plant:**
- **Si (Silicon):**
- Diatoms are known to have cell walls made of opaline silica. Therefore, Si matches with Diatoms.
- **Match:** Si → Diatoms (1 → i)

- **Na (Sodium):**
- Halophytes are plants that thrive in saline environments, which means they have a higher concentration of sodium. Thus, Na matches with Halophytes.
- **Match:** Na → Halophytes (2 → ii)

- **Co (Cobalt):**
- Microbes, particularly certain bacteria, require cobalt for processes such as nitrogen fixation. Hence, Co matches with Microbes.
- **Match:** Co → Microbes (3 → iii)

- **Al (Aluminum):**
- Ferns are known to absorb aluminum from the soil, making Al match with Ferns.
- **Match:** Al → Ferns (4 → iv)

4. **Final Matching:**
- Based on the analysis, we can summarize the matches as follows:
- 1. Si → i. Diatoms
- 2. Na → ii. Halophytes
- 3. Co → iii. Microbes
- 4. Al → iv. Ferns

### Final Matches:
- 1. Si → i. Diatoms
- 2. Na → ii. Halophytes
- 3. Co → iii. Microbes
- 4. Al → iv. Ferns
