The disease of sickle cell anemia is caused due to whose abnormality?

The disease of sickle cell anemia is caused due to the abnormality of (b) Red blood cell. It is a genetic disorder characterized by the presence of abnormal hemoglobin, specifically hemoglobin S. This mutation causes red blood cells to assume a rigid, sickle-like shape under certain conditions, leading to blockages in blood vessels, reduced oxygen delivery to tissues, and various complications such as pain crises, organ damage, and anemia. Unlike white blood cells (a), platelets (c), or blood plasma composition (d), which play essential roles in immune response, clotting, and maintaining blood volume, sickle cell anemia primarily affects the structure and function of red blood cells.
