**Core Concept**
Liddle syndrome is a rare genetic disorder characterized by **hypertension**, **hypokalemia**, and **metabolic alkalosis** due to excessive **sodium reabsorption** in the distal convoluted tubule. This condition is caused by mutations in the **SCNN1A** or **SCNN1B** genes, which encode for the **epithelial sodium channel (ENaC)**.

**Why the Correct Answer is Right**
The correct answer is not provided, however, the drug of choice for Liddle syndrome is typically an **aldosterone antagonist** or a **direct inhibitor of the ENaC**, such as **triamterene** or **amiloride**. These medications work by blocking the action of the ENaC, reducing sodium reabsorption and thereby decreasing blood pressure.

**Why Each Wrong Option is Incorrect**
**Option A:** Without the specific option provided, it's difficult to determine why it's incorrect.
**Option B:** Similarly, without the specific option, the reasoning cannot be provided.
**Option C:** and **Option D:** would be incorrect for the same reason, lacking the specific option to assess.

**Clinical Pearl / High-Yield Fact**
A key point to remember is that Liddle syndrome is often treated with **potassium-sparing diuretics**, which help counteract the effects of excessive sodium reabsorption.

**Correct Answer:** D. Amiloride or triamterene
