Liver cancer is often associated with which of the following viruses?

Liver cancer is closely associated with Hepatitis B virus. This virus can lead to chronic liver infection and is a major risk factor for developing hepatocellular carcinoma, the most common type of liver cancer. Hepatitis B can cause inflammation of the liver, leading to chronic liver disease, cirrhosis, and ultimately, cancer.

Hepatitis A primarily causes acute liver disease but does not lead to chronic infection or cancer. HIV is primarily associated with immunosuppression and increased risk of various cancers, but it is not directly linked to liver cancer. Herpes Simplex virus, while it can cause significant health issues, is not directly associated with liver cancer either. This highlights the unique relationship between Hepatitis B and liver cancer, making it the correct choice.
