[2025-09-30T07:49:02.928570] [PI reasoning] **Identifying the false statement**

I need to identify which statement is false regarding giant cell tumors of bone. I know that these tumors usually affect individuals aged 20-40, which is true. The matrix consists of mononuclear stromal cells, which is also true. However, the claim that osteoclast-like giant cells are the proliferative component is false. So, Option C, stating that "osteoclast giant cells constitute the proliferative component of the tumor," is incorrect. I'll find citations to support this.
