Answer to Question 1
Ans: A
Folic acid deficiency in pregnant women can lead to neural tube deficits like spina bifida in the fetus. Because fetal neural development begins so early in pregnancy, women in their childbearing years must have adequate folic acid intake. Deficiency in vitamin D intake leads to inadequate absorption of calcium and phosphorus, and a deficiency of mineralization in bones and teeth. Increased hemolysis of red blood cells, poor reflexes, impaired neuromuscular functioning, and anemias are signs of vitamin E deficiency, not folic acid deficiency.
