**Core Concept**
Hodgkin's disease, also known as Hodgkin lymphoma, is a type of lymphoma characterized by the presence of distinctive cells called Reed-Sternberg cells. Prognosis in Hodgkin's disease is determined by various factors including age, stage, and response to treatment. Good prognostic features are associated with improved outcomes and survival.

**Why the Correct Answer is Right**
Good prognostic features in Hodgkin's disease include:
- **Age**: Younger patients tend to have a better prognosis than older patients.
- **Stage**: Early-stage disease (I and II) is associated with a better prognosis than advanced-stage disease (III and IV).
- **Lymphocyte predominance**: A subtype of Hodgkin lymphoma with a high number of lymphocytes, which is associated with a better prognosis.
- **Absence of B symptoms**: Patients without symptoms such as fever, weight loss, or night sweats tend to have a better prognosis.

**Clinical Pearl / High-Yield Fact**
In Hodgkin's disease, the presence of **B symptoms** (fever, weight loss, or night sweats) is associated with a worse prognosis. This is because B symptoms indicate a more aggressive disease and a higher risk of disease progression.

**Correct Answer: D.**
