Vedclass · Answer

(D) Pernicious anemia is a condition caused by a deficiency of Vitamin $B_{12}$ in the body.In this condition,red blood cells $(RBCs)$ become larger than normal,which is also known as megaloblastic anemia.The deficiency of Vitamin $B_{12}$ leads to an increased maturation time for erythroblasts (precursor cells of red blood cells),resulting in the presence of immature and abnormally large cells in the blood.Therefore,all the given options are characteristics of pernicious anemia.
