**Core Concept**
Jaundice and white stools are indicative of a liver or biliary system disorder. The patient's symptoms suggest a problem with bilirubin processing, which is a key function of the liver. Bilirubin is a byproduct of heme catabolism, and its metabolism involves several enzymes.

**Why the Correct Answer is Right**
In a patient with jaundice and white stools, elevated levels of alkaline phosphatase (ALP) and gamma-glutamyl transferase (GGT) are common due to cholestasis or bile duct obstruction. However, elevated levels of alanine aminotransferase (ALT) and aspartate aminotransferase (AST) suggest hepatocellular injury, which may be due to hepatitis or other liver conditions. The correct enzyme not raised in this scenario is lactate dehydrogenase (LDH), as it is primarily associated with muscle and red blood cell damage, rather than liver or biliary system disorders.

**Why Each Wrong Option is Incorrect**
**Option A:** Alkaline phosphatase (ALP) is often elevated in conditions involving cholestasis or bile duct obstruction, making it an incorrect choice.
**Option B:** Gamma-glutamyl transferase (GGT) is another enzyme that is commonly elevated in cholestasis or bile duct obstruction, making it an incorrect choice.
**Option C:** Alanine aminotransferase (ALT) is often elevated in conditions involving hepatocellular injury, such as hepatitis, making it an incorrect choice.

**Clinical Pearl / High-Yield Fact**
When evaluating a patient with jaundice and white stools, it's essential to consider the pattern of enzyme elevation to differentiate between hepatocellular and cholestatic liver injury.

**Correct Answer:** D.
