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 of identifying the correctly matched duo of a drug that lowers lipid levels in the blood and its source, we will analyze each option provided.

### Step-by-Step Solution:

1. **Analyze the First Option: Streptokinase**
- **Function**: Streptokinase is known for its role in dissolving blood clots.
- **Source**: It is derived from Streptococcus bacteria.
- **Conclusion**: Since it does not lower lipid levels, this option is incorrect.

2. **Analyze the Second Option: Statins**
- **Function**: Statins are known to lower cholesterol levels and reduce lipid levels in the blood.
- **Source**: The option states Clostridium, which is incorrect. Statins are actually derived from the fungus Monascus purpureus.
- **Conclusion**: While statins do lower lipid levels, the source mentioned is wrong, making this option incorrect.

3. **Analyze the Third Option: Cyclosporine A**
- **Function**: Cyclosporine A is primarily used to prevent organ rejection in transplant patients.
- **Source**: It is obtained from Trichoderma.
- **Conclusion**: This drug does not lower lipid levels, so this option is also incorrect.

4. **Analyze the Fourth Option: Statins**
- **Function**: As previously mentioned, statins effectively lower cholesterol and lipid levels in the blood.
- **Source**: The option correctly states Monascus purpureus as the source.
- **Conclusion**: This option is correct as it matches both the drug and its source accurately.

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