Which type of anemia results from deficiency of all the blood's formed elements, caused by failure of the bone marrow to generate enough new cells?

1. Sickle cell anemia

2. Folic acid deficiency anemia

3. Aplastic anemia

4. Iron deficiency anemia

The correct answer is: Aplastic anemia

Aplastic anemia is the correct answer. This type of anemia results from the failure of the bone marrow to generate enough new cells, leading to a deficiency of all the blood's formed elements. In aplastic anemia, there is a reduction in red blood cells, white blood cells, and platelets due to bone marrow suppression or failure. Sickle cell anemia is a genetic disorder characterized by abnormal hemoglobin that causes red blood cells to become rigid and sickle-shaped, leading to various complications. Folic acid deficiency anemia is caused by a lack of folate in the diet, leading to impaired red blood cell production. Iron deficiency anemia is characterized by a lack of iron, leading to inadequate production of hemoglobin and red blood cells.
