**Core Concept**
The question is testing the association between a specific clinical condition, yellow/fatty liver, and its characteristic pathophysiological correlate.

**Why the Correct Answer is Right**
Yellow/fatty liver is typically seen in conditions where there is an accumulation of lipids in the liver cells. This is often due to an imbalance between the uptake and oxidation of fatty acids in the liver. Conditions like obesity, diabetes, and excessive alcohol consumption can lead to this imbalance.

**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect because it doesn't specify the underlying pathophysiology leading to yellow/fatty liver.
**Option B:** This option is incorrect because it doesn't accurately describe the characteristic clinical presentation of yellow/fatty liver.
**Option C:** This option is incorrect because it doesn't provide a clear link between the condition and the pathophysiological mechanism leading to yellow/fatty liver.

**Clinical Pearl / High-Yield Fact**
The presence of yellow/fatty liver is often associated with non-alcoholic fatty liver disease (NAFLD), a condition characterized by excessive fat accumulation in the liver of individuals who consume little or no alcohol.

**Correct Answer: D. Wilson's disease**
