Solution
The correct option is C Spleen
Spleen, made of lymphatic tissues, is known as the graveyard of RBCs. It acts as a reservoir for erythrocytes and can regulate the number in circulation. It is also the site for the breakdown of worn-out erythrocytes and stores the iron generated. Liver cells degrade the haemoglobin of worn-out erythrocytes or red blood corpuscles into bile pigments (bilirubin and biliverdin).The life of an RBC is about 120 days.
