Multiple myeloma is cancer affecting:

Lymph nodes
Bone marrow
Blood vessels
The skin

The correct answer is: Bone marrow

Multiple myeloma is a type of cancer that specifically affects the bone marrow. In multiple myeloma, there is an uncontrolled growth of plasma cells in the bone marrow, leading to the production of abnormal antibodies and crowding out normal blood cells. This can result in bone pain, fractures, anemia, and impaired immune function. Therefore, the correct answer is B. The other options are incorrect because: A. Lymph nodes are not the primary site affected in multiple myeloma. C. While multiple myeloma does involve abnormal plasma cells circulating in the blood, it primarily affects the bone marrow. D. Multiple myeloma does not affect the skin; its primary impact is on the bone marrow.
