**Core Concept**
Common bile duct (CBD) stones are a type of gallstone that becomes lodged in the CBD, leading to obstructive jaundice. The clinical manifestations of CBD stones are primarily due to the obstruction of bile flow, resulting in increased bilirubin levels and subsequent jaundice.

**Why the Correct Answer is Right**
The clinical manifestations of CBD stones include obstructive jaundice, which is characterized by the presence of jaundice, dark urine, and pale stools. The increased bilirubin levels lead to a rise in conjugated bilirubin, which is responsible for the yellowish discoloration of the skin and mucous membranes. The obstruction of the CBD also leads to an increase in the levels of alkaline phosphatase, a liver enzyme that is elevated in cases of cholestasis.

**Clinical Pearl / High-Yield Fact**
It's essential to remember that the clinical manifestations of CBD stones can be subtle, and the diagnosis often requires a combination of laboratory tests, imaging studies, and endoscopic retrograde cholangiopancreatography (ERCP). The presence of jaundice, dark urine, and pale stools should prompt further investigation for CBD stones.
