Red marrow produces which type of blood cells?

• A. White blood cells
• B. Platelets
• C. Plasma
• D. Red blood cells

Answer: (D)

Red marrow is the site where blood cells are formed, a process known as hematopoiesis. In adults, it produces the main formed elements: red blood cells, white blood cells, and platelets. The option that names a blood cell type produced by red marrow is red blood cells, the oxygen-carrying cells formed through erythropoiesis. Plasma, by contrast, is not a cell at all; it’s the liquid component of blood. So, while red marrow makes several cell types, red blood cells are the classic cell type associated with marrow activity in this context.
