The right answer is Vitamin B9 (folic acid).

Before and during pregnancy, supplementation with folic acid (or folate, or vitamin B9) is recommended. A deficiency in this vitamin can indeed be at the origin of serious malformations of the nervous system of the fetus such as spina bifida. The ideal is to start supplementation at the earliest because the nervous system develops in the first weeks of pregnancy.
