D. Statins - Cholesterol lowering agent

Answer

To solve the question "Select the correct match," we need to analyze each option provided and determine if the organism and the product listed are correctly matched.

### Step-by-Step Solution:

1. **Analyze Option A: Aspergillus niger - Acetic Acid**
- Aspergillus niger is a fungus known for its role in the production of citric acid, not acetic acid. Acetic acid is primarily produced by the bacterium Acetobacter.
- **Conclusion:** This is an incorrect match.

2. **Analyze Option B: Streptokinase - Clot Buster**
- Streptokinase is indeed produced by the bacterium Streptococcus. It is used as a clot buster in medical treatments, especially for myocardial infarction.
- **Conclusion:** This is a correct match.

3. **Analyze Option C: Cyclosporine A - Clot Buster**
- Cyclosporine A is not a clot buster; it is an immunosuppressive agent used to prevent organ rejection in transplant patients. It is produced by the fungus Tolypocladium inflatum (previously known as Trichoderma polysporum).
- **Conclusion:** This is an incorrect match.

4. **Analyze Option D: Statins - Cholesterol Lowering Agent**
- Statins are indeed used as cholesterol-lowering agents and are produced by the yeast Monascus purpureus. They work by inhibiting the enzyme responsible for cholesterol synthesis.
- **Conclusion:** This is a correct match.

### Final Answer:
The correct match among the options is **Option D: Statins - Cholesterol Lowering Agent.**
