• A. Iron
• B. Vitamin C
• C. Calcium
• D. Folic acid

It plays a vital role in the development of the neural tube in the fetus, reducing the risk of defects such as spina bifida and anencephaly. It is recommended that women of childbearing age consume adequate amounts of folic acid, either through diet or supplements, to support a healthy pregnancy and prevent these serious birth defects.
