## Core Concept
Hepatoblastoma is a rare malignant liver tumor that primarily affects children, often presenting in the first few years of life. It is believed to originate from the primitive hepatic cells (hepatoblasts) and can exhibit a range of histological patterns. The tumor's behavior and treatment outcomes vary significantly depending on its histology, stage at diagnosis, and the patient's overall health.

## Why the Correct Answer is Right
To accurately determine why the correct answer is right, the specific statements associated with options A, B, C, and D need to be provided. However, in the context of hepatoblastoma, common true statements include its association with genetic syndromes (like Beckwith-Wiedemann syndrome), elevated alpha-fetoprotein (AFP) levels, and its potential for surgical resection as a primary treatment. Without specific details on the options, a general understanding is that hepatoblastoma is a unique pediatric liver cancer with distinct characteristics.

## Why Each Wrong Option is Incorrect
Given the lack of specific details on the options, let's hypothetically analyze:
- **Option A:** If a statement claims hepatoblastoma exclusively affects adults, it would be incorrect because hepatoblastoma predominantly occurs in children.
- **Option B:** If a statement suggests that hepatoblastoma is always associated with cirrhosis, it would be incorrect because, unlike hepatocellular carcinoma in adults, hepatoblastoma is not typically associated with underlying liver cirrhosis.
- **Option C:** If a statement says hepatoblastoma never responds to chemotherapy, it would be incorrect because chemotherapy is indeed a part of the treatment regimen for many cases of hepatoblastoma.
- **Option D:** If a statement claims AFP levels are always normal in hepatoblastoma, it would be incorrect because elevated AFP levels are commonly observed in patients with hepatoblastoma.

## Clinical Pearl / High-Yield Fact
A key point to remember is that **alpha-fetoprotein (AFP) levels are often elevated in hepatoblastoma**, serving as a useful tumor marker for diagnosis and monitoring response to treatment. This is a critical clinical correlation that can aid in the management of patients suspected to have hepatoblastoma.

## Correct Answer: D.
