Choose the correctly matched duo of the drug which lowers lipid levels in the blood and its source.

Options

A. Drug: Streptokinase, Organism : Streptococcus
B. Drug : Statins, Organism: Clostridium
C. Drug: Cyclosporin A, Organism : Trichoderma
D. Drug : Statins, Organism : Monascus

Answer

To solve the question, we need to identify which drug is correctly matched with its function of lowering lipid levels in the blood and its source. Let's analyze each option step by step.

### Step 1: Analyze Option A - Streptokinase
- **Function**: Streptokinase is known for dissolving blood clots, not lowering lipid levels.
- **Source**: It is derived from the bacterium Streptococcus.
- **Conclusion**: This option is incorrect because, although the source is correct, the function does not match.

**Hint**: Remember that not all drugs that have a source related to bacteria are used for lowering lipid levels.

### Step 2: Analyze Option B - Statins
- **Function**: Statins are indeed known to lower lipid levels in the blood.
- **Source**: The statement claims it is derived from Clostridium, which is incorrect. Statins are derived from Monascus.
- **Conclusion**: This option is incorrect because the source is mismatched.

**Hint**: Focus on the correct source of the drug when determining if the option is valid.

### Step 3: Analyze Option C - Cyclosporine A
- **Function**: Cyclosporine A is an immunosuppressant and does not lower lipid levels.
- **Source**: It is derived from the fungus Tolypocladium inflatum (previously known as Dicoderma).
- **Conclusion**: This option is incorrect because the function does not match.

**Hint**: Consider the primary use of the drug to determine if it fits the requirement of lowering lipid levels.

### Step 4: Analyze Option D - Statins
- **Function**: Statins lower lipid levels in the blood.
- **Source**: The correct source of statins is Monascus.
- **Conclusion**: This option is correct as both the function and source are accurately matched.

**Hint**: Verify both the function and source for a complete match.

### Final Answer:
The correctly matched duo of the drug which lowers lipid levels in the blood and its source is **Option D: Statins derived from Monascus**.
