Which of the following micronutrients should be supplemented for pregnant women in order to prevent birth defect? a . Cholecalciferol b. Calcium c. Iron d. Folate Exam Navigation III

The correct answer is d. Folate.<br /><br />Folate, also known as vitamin B9, is essential for pregnant women to prevent birth defects, particularly neural tube defects in the developing fetus. Neural tube defects can lead to serious congenital disabilities, such as spina bifida and anencephaly.<br /><br />Folate plays a crucial role in DNA synthesis, cell division, and proper fetal development. Pregnant women are advised to consume adequate amounts of folate-rich foods or take folic acid supplements before conception and during early pregnancy to reduce the risk of neural tube defects.<br /><br />While cholecalciferol (vitamin D3), calcium, and iron are also important micronutrients for pregnant women, folate is specifically recommended for the prevention of birth defects.
