Question

The $RBC$ deficiency is deficiency disease of :

• A. Vitamin $B_{12}$
• B. Vitamin $B_6$
• C. Vitamin $B_1$
• D. Vitamin $B_2$

Answer 1

The Correct Option is A

The deficiency of Red Blood Cells (RBCs), often termed as anemia, is commonly associated with Vitamin $B_{12}$ deficiency. This condition is specifically known as pernicious anemia. Vitamin $B_{12}$ is crucial for the production and maturation of red blood cells. Without sufficient Vitamin $B_{12}$, the body cannot produce enough healthy red blood cells, leading to a deficiency.

Let's analyze the options to understand why Vitamin $B_{12}$ is the correct answer:

• Vitamin $B_{12}$: Deficiency leads to pernicious anemia due to its vital role in red blood cell formation and neurological function.
• Vitamin $B_6$: Although important for heme synthesis, its deficiency usually causes microcytic anemia, which is different from the anemia caused by Vitamin $B_{12}$ deficiency.
• Vitamin $B_1$ (Thiamine): Deficiency results in diseases like beriberi and Wernicke-Korsakoff syndrome, not directly related to RBC deficiency.
• Vitamin $B_2$ (Riboflavin): Its deficiency causes ariboflavinosis, which affects the skin and mucous membranes but not directly the RBC count.

Thus, the correct answer is Vitamin $B_{12}$.
