Yes you are right. I got it completely wrong. The question says who removes the dead RBCs not in which organs does it dies. The removal of dead cells are mainly disposed off by Liver. So Liver should be the correct answer

Ans is A. Old or damaged RBCs are removed from the circulation by macrophages in the spleen and liver, and the hemoglobin they contain is broken down into heme and globin. The globin protein may be recycled, or broken down further to its constituent amino acids, which may be recycled or metabolized............ * First of all i want to say that matured RBCs calls “red blood capsules” in mammals. It have no nucleus. When RBCs dead, they are transported to spleen which is also known as graveyard of rbcs. here these are digested by several lysase enzymes. Here it’s heme constituent of hemoglobin are broken down into Fe3+ and . The biliverdin is reduced to , which is released into the plasma and recirculated to the liver bound to . The iron is released into the plasma to be recirculated by a carrier protein called . Almost all erythrocytes are removed in this manner from the circulation before they are old enough to . Hemolyzed hemoglobin is bound to a protein in plasma called which is not excreted by the kidney.". This process calls “Eryptosis”.
