D Correct answer
Explanation

Red blood cells (erythrocytes) are produced in the bone marrow through a process called erythropoiesis. In adults, this primarily occurs in the flat bones like the sternum, ribs, and pelvis. The liver produces red blood cells only during fetal development, while the spleen filters and stores old red blood cells rather than producing them.
