Chronic liver disease is caused by -a) Hepatitis Bb) Hepatitis Ac) Hepatitis Cd) Hepatitis E

**Core Concept**
Chronic liver disease is a condition characterized by persistent inflammation and damage to the liver, leading to fibrosis and cirrhosis. This condition can be caused by various viral infections, including hepatitis viruses.

**Why the Correct Answer is Right**
Hepatitis B and C are the most common causes of chronic liver disease. Hepatitis B virus (HBV) can cause chronic infection, leading to liver cirrhosis and hepatocellular carcinoma. Hepatitis C virus (HCV) is also highly virulent and can cause chronic infection, leading to liver fibrosis and cirrhosis. Both HBV and HCV can establish persistent infections, making them the primary causes of chronic liver disease.

**Why Each Wrong Option is Incorrect**
**Option A:** Hepatitis B is a correct cause of chronic liver disease, but there is another option that is also a common cause.
**Option B:** Hepatitis A is primarily a self-limiting infection and does not typically cause chronic liver disease.
**Option C:** Hepatitis C is a correct cause of chronic liver disease, but there is another option that is also a common cause.
**Option D:** Hepatitis E is primarily a self-limiting infection and is not commonly associated with chronic liver disease.

**Clinical Pearl / High-Yield Fact**
It is essential to note that chronic liver disease can also be caused by non-viral factors, such as alcohol abuse, non-alcoholic steatohepatitis (NASH), and genetic disorders.

**Correct Answer: C. Hepatitis C**
