Match column I with column II and select the correct option
List 1`" "`List 2
Citric acid`" "`Trichoderma
Cyclosporin A`" "`Clostridium
Statins`" "`Aspergillus
Butyric acid`" "`Monascus

Answer

To solve the matching question, we need to pair the substances in List 1 with their corresponding sources in List 2. Let's go through each item step by step:

### Step 1: Identify the source of Citric Acid
- **Citric Acid** is primarily produced by the fungus **Aspergillus niger**.
- Therefore, we match **Citric Acid** with **Aspergillus**.

### Step 2: Identify the source of Cyclosporin A
- **Cyclosporin A** is produced by the fungus **Trichoderma**.
- Thus, we match **Cyclosporin A** with **Trichoderma**.

### Step 3: Identify the source of Statins
- **Statins** are produced by the fungus **Monascus**.
- Hence, we match **Statins** with **Monascus**.

### Step 4: Identify the source of Butyric Acid
- **Butyric Acid** is produced by the bacterium **Clostridium**.
- Therefore, we match **Butyric Acid** with **Clostridium**.

### Summary of Matches
- **Citric Acid** → **Aspergillus**
- **Cyclosporin A** → **Trichoderma**
- **Statins** → **Monascus**
- **Butyric Acid** → **Clostridium**

### Final Matching
- A (Citric Acid) → 3 (Aspergillus)
- B (Cyclosporin A) → 1 (Trichoderma)
- C (Statins) → 4 (Monascus)
- D (Butyric Acid) → 2 (Clostridium)

### Answer
The correct matches are:
- A → 3
- B → 1
- C → 4
- D → 2
