[A]: Albumin is associated with oedema.
[R]: It is produced by liver.

Options

A. If both A and R are true and R is the correct explanation of A
B. If both A and R are true but R is not the correct explanation of A
C. If A is true and R is false
D. If both A and R are false

Answer

### Step-by-Step Solution:

1. **Understanding Albumin**:
- Albumin is a type of protein found in the blood. It is classified as a plasma protein and plays a crucial role in maintaining oncotic pressure, which helps keep fluid within the blood vessels.

2. **Production of Albumin**:
- Albumin is synthesized in the liver. This means that the liver is responsible for producing this important protein.

3. **Association with Edema**:
- Edema is a condition characterized by an excess of fluid in the tissues. When albumin levels in the blood are low, it can lead to a decrease in oncotic pressure, causing fluid to leak out of the blood vessels and accumulate in the surrounding tissues, resulting in edema.

4. **Evaluating Statements A and R**:
- Statement A: "Albumin is associated with edema." This statement is true because low levels of albumin can lead to edema.
- Statement R: "It is produced by the liver." This statement is also true because albumin is synthesized in the liver.

5. **Determining the Relationship**:
- While both statements A and R are true, the relationship between them needs to be evaluated. Statement R (the production of albumin by the liver) does not directly explain why albumin is associated with edema. Instead, it is the low levels of albumin that lead to edema, not merely the fact that it is produced by the liver.

6. **Conclusion**:
- Therefore, both statements A and R are true, but R is not the correct explanation for A. The final answer is that both A and R are true, but R does not explain A.
