A. Hepatocellular adenoma
B. Hepatocellular carcinoma
C. Angiomyolipoma
D. Hemangioma

**Core Concept:** Benign liver tumors are rare compared to malignant ones, but some are more common than others. These include hepatocellular adenomas, carcinomas, angiomyolipomas, and hemangiomas.

**Why the Correct Answer is Right:** Hepatocellular adenoma (A) is the most common benign liver tumor. It is a benign neoplasm originating from hepatocytes and is usually caused by the use of oral contraceptives.

**Why Each Wrong Option is Incorrect:**

- Hepatocellular carcinoma (B) is the most common malignant liver tumor, not a benign one.
- Angiomyolipoma (C) is a rare benign tumor of the kidney, not liver.
- Hemangioma (D) is a benign tumor of blood vessels, not hepatocytes.

**Clinical Pearl:** Benign liver tumors are typically managed conservatively as they are generally asymptomatic or grow slowly. In some cases, surgery may be required for complications like rupture or bleeding.

**Correct Answer:** Hepatocellular adenoma (A) is the commonest benign tumor of liver.
