**Core Concept**
The **liver** is divided into segments based on the **hepatic ducts** and **portal vein** branching. The **right hepatic duct** is responsible for draining segments of the liver.

**Why the Correct Answer is Right**
The **right hepatic duct** typically drains segments V, VI, VII, and VIII. However, it does not drain segment IV, which is drained by the **left hepatic duct**. This is because segment IV is part of the left liver lobe.

**Why Each Wrong Option is Incorrect**
**Option A:** Incorrect because segment V is drained by the right hepatic duct.
**Option B:** Incorrect because segment VI is also drained by the right hepatic duct.
**Option C:** Incorrect because segment VII is drained by the right hepatic duct.
**Option D:** This option is not provided, but typically segment IV would be the correct answer as it is drained by the left hepatic duct.

**Clinical Pearl / High-Yield Fact**
Remember that the **liver segments** are defined by the **hepatic duct** and **portal vein** branching, and the **right hepatic duct** typically drains the right liver lobe, except for segment IV.

**Correct Answer: D. Segment IV**
