Answer

### Step-by-Step Solution:

1. **Understanding Cyclosporin A**:
- Cyclosporin A is a medication that is primarily used as an immunosuppressive agent. This means it helps to suppress the immune system to prevent the rejection of transplanted organs.

2. **Source of Cyclosporin A**:
- Cyclosporin A is produced by a fungus known as *Trichoderma polyspora*. This is an important fact as it identifies the biological origin of the drug.

3. **Application of Cyclosporin A**:
- The primary application of Cyclosporin A is in patients who have undergone organ transplants. It is used to prevent graft rejection, which is when the body’s immune system attacks the transplanted organ.

4. **Evaluating the Statements**:
- Now, we need to evaluate the given statements:
- **Statement 1**: "It is produced by the fungus Trichoderma polyspora." - This statement is **correct**.
- **Statement 2**: "It is used as an immunosuppressive agent during organ transplant." - This statement is also **correct**.
- **Statement 3**: "It is produced by the yeast Monascus purpureus." - This statement is **incorrect**. Monascus purpureus is known for producing statins, which are used to lower cholesterol, not cyclosporin A.

5. **Conclusion**:
- Based on the evaluation of the statements, the correct statements about Cyclosporin A are Statements 1 and 2.

### Final Answer:
Both Statement 1 and Statement 2 are correct regarding Cyclosporin A.
