Oedema is the correct answer because it refers to the condition when a lymph node becomes blocked. Oedema is the accumulation of excess fluid in the body tissues, often causing swelling.

Explanation
Oedema, or the accumulation of fluid in the body tissues, can be caused by various factors. Liver diseases such as cirrhosis can lead to fluid retention due to impaired liver function. Kidney diseases, such as nephrotic syndrome or renal failure, can also cause oedema as the kidneys are responsible for regulating fluid balance in the body. Inflammatory conditions, such as arthritis or infections, can cause oedema due to the body's immune response and increased blood flow to the affected area. These three factors - liver diseases, kidney diseases, and inflammatory conditions - can all contribute to the development of oedema.
