An unnecessarily large number of immature nucleated RBCs are found in the blood of an infected person. To get rid of this condition, which of the following would you recommend in a balanced diet?

Correct option is B

Ans. (b) Vitamin B12 and Folic Acid
Sol. A high number of immature nucleated RBCs in the blood is a sign of Megaloblastic Anemia, which is caused by a deficiency of Vitamin B12 and Folic Acid. These vitamins are essential for DNA synthesis and proper red blood cell maturation in the bone marrow. Their deficiency leads to abnormally large, immature RBCs with nuclei that do not function properly.
Explanation of each option:
· (a) Protein – Important for general cell function, but not directly involved in RBC maturation.
· (b) Vitamin B12 and Folic Acid – Correct answer. Their deficiency causes Megaloblastic Anemia, leading to nucleated RBCs in the blood.
· (c) Vitamin K – Essential for blood clotting, but not for RBC production.
· (d) Iron – Necessary for hemoglobin formation, but iron deficiency causes microcytic anemia, not nucleated RBCs.
