Which type of anemia is caused by a lack of essential nutrients?

Explanation

Megaloblastic anemia results from deficiencies in vital nutrients such as vitamin B12 or folate, making it a nutritional deficiency anemia. In contrast, aplastic anemia involves bone marrow failure, sickle cell anemia is a genetic disorder affecting hemoglobin structure, and hemolytic anemia is caused by premature destruction of red blood cells.
