Which disease is a viral infection that leads to swelling of the liver?

• A. Hemorrhoids
• B. Gastroesophageal Reflux Disease
• C. Irritable Bowel Syndrome
• D. Hepatitis C

Answer: (D)

Hepatitis C is a viral infection that causes inflammation of the liver, leading to swelling (hepatomegaly). Among the options, it uniquely fits as a liver-targeted viral disease, whereas the others are non-viral conditions affecting different parts of the GI tract or its surroundings. Hemorrhoids involve veins around the anus, GERD is acid reflux into the esophagus, and irritable bowel syndrome is a functional bowel disorder. So the correct choice highlights a viral infection that inflames the liver.
