Match Column - I with Column - II and select the correct option using the codes given below :
`{:(,"Column-I", ,"Column-II"),(a., "Citric acid",(i),"Trichoderma"),(b.,"Cyclosporin A",(ii),"Clostridum"),(c.,"Statins",(iii),"Aspergillus"),(d.,"Butyric acid",(iv),"Monascus"):}`

Options

A. `{:(a,b,c,d),("(iii)","(i)","(ii)","(iv)"):}`
B. `{:(a,b,c,d),("(iii)","(i)","(iv)","(ii)"):}`
C. `{:(a,b,c,d),("(i)","(iv)","(ii)","(iii)"):}`
D. `{:(a,b,c,d),("(iii)","(iv)","(i)","(ii)"):}`

Answer

To solve the matching question, we need to correctly pair the items in Column-I with their corresponding items in Column-II based on the information provided about each substance and its source.

### Step-by-Step Solution:

1. **Identify the Source of Citric Acid**:
- Citric acid is produced through fermentation by a fungus. The specific fungus known for this is **Aspergillus niger**.
- **Match**: Citric Acid (a) → Aspergillus (iii)

2. **Identify the Source of Cyclosporin A**:
- Cyclosporin A is an immunosuppressive agent derived from the fungus **Trichoderma**.
- **Match**: Cyclosporin A (b) → Trichoderma (i)

3. **Identify the Source of Statins**:
- Statins are cholesterol-lowering agents obtained from the yeast **Monascus purpureus**.
- **Match**: Statins (c) → Monascus (iv)

4. **Identify the Source of Butyric Acid**:
- Butyric acid is produced by the bacterium **Clostridium butylicum**.
- **Match**: Butyric Acid (d) → Clostridium (ii)

### Final Matches:
- a → (iii) Aspergillus
- b → (i) Trichoderma
- c → (iv) Monascus
- d → (ii) Clostridium

### Summary of Matches:
- A (Citric Acid) → (iii) Aspergillus
- B (Cyclosporin A) → (i) Trichoderma
- C (Statins) → (iv) Monascus
- D (Butyric Acid) → (ii) Clostridium

### Correct Option:
The correct option based on the matches is:
- A3, B1, C4, D2
