The main idea is the functional and cellular distinction between the spleen’s red pulp and white pulp. Red pulp is the blood-filtering part, packed with many red blood cells and macrophages that remove old or damaged RBCs from circulation; it also serves as a reservoir for platelets and blood. White pulp is lymphoid tissue that supports the immune response to blood-borne antigens, housing lymphocytes organized around central arteries (T cells in the periarterial lymphatic sheath and B cells in follicles).

So the correct statement reflects this difference: red pulp contains large quantities of red blood cells, while white pulp contains lymphocytes. The other options don’t capture the key functional contrast (iron recycling occurs in macrophages but isn’t the defining difference, and white pulp isn’t primarily a neutrophil area; the red versus white pulp distinction isn’t related to scent or taste).
