The correct answer is C) Vitamin B12 deficiency.
Macrocytic anemia is characterized by larger-than-normal red blood cells, and the most common cause is a deficiency in Vitamin B12 (cobalamin). Vitamin B12 plays a crucial role in the production of red blood cells, and a deficiency can lead to impaired DNA synthesis, causing the production of larger, immature red blood cells.
