Megaloblastic anemia is a type of

• A. Pernicious anemia
• B. Aplastic anemia
• C. Megaloblastic anemia
• D. Iron-deficiency anemia

Answer: (C)

This item tests how anemia is classified by its underlying process and appearance. Megaloblastic anemia is defined by defective DNA synthesis in red blood cell precursors, which causes the cells to grow large (macrocytosis) and develop as megaloblasts. It’s usually due to deficiencies of vitamin B12 or folate. When the question asks what category this condition belongs to, the most fitting choice is the disorder itself, because it’s naming the type of anemia. The other options point to different conditions: aplastic anemia is a bone marrow failure state, iron-deficiency anemia is a microcytic anemia from iron shortage, and pernicious anemia is a cause of B12 deficiency that can lead to megaloblastic changes but is not the broad classification itself.
