where are dead red blood cells phagocytosed?
lymph nodes
red pulp of spleen
peryers patches
white pulp of spleen

Explanation:

Dead red blood cells are phagocytosed in the red pulp of the spleen. Lymph nodes filter lymph, Peyer's patches are in the intestine (for immune response to gut antigens), and white pulp of the spleen is for immune functions (not phagocytosis of dead RBCs). The red pulp contains macrophages that remove old/damaged RBCs.

Answer:

B. Red pulp of spleen
