So yes your best bet is B.
Neural tube defects are birth defects of the brain and spine.
<u>Explanation:</u>
Neural tube abnormalities are brain, spine or spinal cord birth defects. These occur during the first month of pregnancy, sometimes even before a woman knows she's expecting. Spina bifida, and anencephaly are the two most common neural tube defects.
