**Core Concept**
Increased lipolysis of fat stores can lead to the accumulation of fat in the liver, resulting in **steatosis** or **fatty liver disease**. This condition is characterized by the excessive storage of **triglycerides** within **hepatocytes**. The underlying mechanism involves the imbalance between the uptake and oxidation of fatty acids in the liver.

**Why the Correct Answer is Right**
The correct answer is related to the increased delivery of **free fatty acids** to the liver, which exceeds the liver's ability to oxidize or export them, leading to the accumulation of **triglycerides**. This process is mediated by the increased activity of **hormone-sensitive lipase**, which breaks down triglycerides in adipose tissue, releasing **free fatty acids** into the bloodstream.

**Why Each Wrong Option is Incorrect**
**Option A:** Incorrect because it does not directly relate to the increased delivery of free fatty acids to the liver.
**Option B:** Incorrect as it is not the primary mechanism by which increased lipolysis leads to steatosis.
**Option C:** Incorrect because, although it may contribute to steatosis, it is not the most direct consequence of increased lipolysis.

**Clinical Pearl / High-Yield Fact**
A key point to remember is that **steatosis** can progress to more severe forms of liver disease, such as **steatohepatitis** and **cirrhosis**, if the underlying cause is not addressed. Recognizing the relationship between increased lipolysis and steatosis is crucial for managing patients with conditions like diabetes mellitus or those on long-term corticosteroid therapy.

**Correct Answer:** D. Increased delivery of free fatty acids to the liver.
