Answer

### Step-by-Step Solution:

1. **Understanding Cyclosporin A**: Cyclosporin A is a medication that acts as an immunosuppressive agent. It is primarily used in medical settings to help prevent the rejection of transplanted organs.

2. **Function of Cyclosporin A**: The main function of Cyclosporin A is to suppress the immune system. This is crucial after organ transplants because the immune system may recognize the new organ as foreign and attempt to reject it.

3. **Context of Use**: Cyclosporin A is specifically used in patients who have received organ transplants, such as kidney, liver, or heart transplants. These patients are at risk of organ rejection, and Cyclosporin A helps to mitigate this risk.

4. **Source of Cyclosporin A**: Cyclosporin A is derived from a type of fungus known as *Trichoderma polysporum*. This natural source is important as it highlights the role of microbes in human welfare, particularly in medicine.

5. **Incorrect Uses**: It is important to note that Cyclosporin A is not used for dissolving blood clots, lowering cholesterol levels, or enhancing the tenderness of meat. These options are incorrect and do not reflect the actual use of Cyclosporin A.

6. **Conclusion**: The correct answer to the question of what Cyclosporin A is used for is that it is an immunosuppressive agent used to prevent organ rejection in transplant patients.
