Answer: D - Megaloblastic anemia may be caused by a deficiency of folic acid, which regulates the formation of red blood cells through its effect on DNA synthesis. Lack of intrinsic factor, a protein found in the small intestine and needed for vitamin B12 absorption; may lead to impaired B12 status, a risk factor for megaloblastic anemia. Gluten-induced enteropathy causes damage to the intestinal mucosa, thereby interfering with absorption of both folic acid and vitamin B12.
