Which nutrient deficiency is listed as a risk factor for Down Syndrome?

Explanation:
Down syndrome risk comes from chromosomal nondisjunction during meiosis, with advancing maternal age being the most consistently reported associated factor. Nutritional status during pregnancy does not determine whether a child has Down syndrome. Folic acid is essential to prevent neural tube defects, but it does not modify or cause Down syndrome risk. So, none of the listed nutrient deficiencies are established risk factors for Down syndrome; folic acid’s important prenatal role is in reducing neural tube defects, not altering Down syndrome risk.
