Vedclass · Answer

(B) The correct answer is $B$. Immature nucleated $RBCs$ (erythroblasts) in the blood indicate a failure in the maturation process of erythrocytes. Vitamin $B_{12}$ (cyanocobalamin) and folic acid are essential co-factors for $DNA$ synthesis and cell division during erythropoiesis in the bone marrow. $A$ deficiency in these vitamins leads to megaloblastic anaemia,where $RBCs$ remain immature and nucleated. Therefore,supplementation with vitamin $B_{12}$ and folic acid is necessary to promote the maturation of these cells.
