To determine which disease affects the liver among the options provided, we need to analyze each option individually.

Option A: Pneumonia - Pneumonia is an infection that primarily affects the lungs and does not directly affect the liver. Therefore, we can eliminate this option.

Option B: Hepatitis - Hepatitis is a disease characterized by inflammation of the liver. This option indicates that the liver is indeed affected. Therefore, we can consider this as a potential answer.

Option C: AIDS - AIDS (Acquired Immunodeficiency Syndrome) is a condition caused by the human immunodeficiency virus (HIV). While HIV can indirectly affect the liver, it is not primarily a liver disease. Therefore, we can eliminate this option.

Option D: Amoebiasis - Amoebiasis is an infection caused by the parasite Entamoeba histolytica. This infection primarily affects the intestines and can lead to liver abscesses. Therefore, the liver is indeed affected in this disease.

Based on the analysis, the diseases that affect the liver among the given options are Hepatitis (Option B) and Amoebiasis (Option D).
