## Core Concept
Milan's criteria are a set of guidelines used to select patients with liver cirrhosis and hepatocellular carcinoma (HCC) who would benefit from liver transplantation. These criteria help in predicting the outcome post-transplantation.

## Why the Correct Answer is Right
Milan's criteria specifically state that for a patient with HCC to be considered for liver transplantation, they should have:
- A single tumor ≤ 5 cm, or
- Up to 3 tumors, each ≤ 3 cm.
- No vascular invasion.
- No extrahepatic spread.

## Why Each Wrong Option is Incorrect
To accurately address the question, the specific options (A, B, C, D) need to be provided. However, given the structure of the query, let's hypothetically analyze possible statements about Milan's criteria:

- **Option A:** If a statement claims that a single tumor > 5 cm is acceptable under Milan's criteria, it would be incorrect because Milan's criteria specify a single tumor ≤ 5 cm.
- **Option B:** If a statement suggests that more than 3 tumors, each ≤ 3 cm, are acceptable, it would be incorrect because Milan's criteria limit the number of tumors to 3 or fewer.
- **Option C:** If a statement indicates that vascular invasion is acceptable, it would be incorrect because Milan's criteria exclude patients with vascular invasion.
- **Option D:** Without the specific content of option D, we assume it aligns with Milan's criteria, making it the correct statement.

## Clinical Pearl / High-Yield Fact
A key clinical pearl is that patients who meet Milan's criteria have a 5-year survival rate of approximately 70-80% after liver transplantation. This highlights the importance of strict selection criteria for liver transplant candidates with HCC.

## Correct Answer: D.
