Trichoderma polysporum is a source of
1)Cyclosporin-A
2) Streptokinase
3) Statins
4) Clot buster

Options

A. Cyclosporin-A
B. Streptokinase
C. Statins
D. Clot buster

Answer

### Step-by-Step Solution:

1. **Identify the Organism**: The question asks about *Trichoderma polysporum*, which is identified as a fungus.

2. **Type of Fungus**: It is specified that *Trichoderma polysporum* is an aerobic fungus, meaning it requires oxygen for its metabolic processes.

3. **Industrial Use**: This fungus is known for its industrial applications, particularly in the production of certain pharmaceuticals.

4. **Specific Drug Production**: The primary drug produced from *Trichoderma polysporum* is **cyclosporine A**. This drug is classified as an immunosuppressive agent.

5. **Function of Cyclosporine A**: Cyclosporine A is used to lower the immune response in patients, particularly in the context of organ transplantation. It helps prevent the body from rejecting a transplanted organ by suppressing the immune system.

6. **Evaluate Other Options**:
- **Streptokinase**: This is an enzyme used as a clot buster, but it is not derived from *Trichoderma polysporum*.
- **Statins**: These are cholesterol-lowering agents, unrelated to *Trichoderma polysporum*.
- **Clot Buster**: This term generally refers to drugs like streptokinase, which dissolve blood clots, but again, this is not produced by *Trichoderma polysporum*.

7. **Conclusion**: Based on the information gathered, the correct answer to the question is that *Trichoderma polysporum* is a source of **cyclosporine A**.

### Final Answer:
*Trichoderma polysporum is a source of Cyclosporin-A.*
