**Core Concept**
Hodgkin lymphoma is a type of lymphoma characterized by the presence of distinctive cells, including Reed-Sternberg cells, lymphocytic and histiocytic (L&H) cells, and lymphocytic and cell-rich (L&H) variants. The disease is a neoplastic proliferation of lymphocytes and their precursors.

**Why the Correct Answer is Right**
In Hodgkin lymphoma, Reed-Sternberg cells and their variants are typically seen, but certain types of cells are not characteristic of this disease. For example, **sinus histiocytes** are not typically seen in Hodgkin lymphoma, as this disease is characterized by a lack of reactive sinus histiocytosis.

**Why Each Wrong Option is Incorrect**
**Option A:** Reed-Sternberg cells are a hallmark of Hodgkin lymphoma, making this option incorrect.
**Option B:** Lymphocytic and histiocytic (L&H) cells are also seen in Hodgkin lymphoma, particularly in the nodular lymphocyte-predominant subtype, making this option incorrect.
**Option C:** While the exact cell type is not specified, lymphocytes are a key component of Hodgkin lymphoma, making this option incorrect.

**Clinical Pearl / High-Yield Fact**
Reed-Sternberg cells can be divided into two main types: classic Reed-Sternberg cells and variants such as L&H cells. The presence of these cells is a key diagnostic feature of Hodgkin lymphoma.

**Correct Answer: D.**
