答案: B.懷孕前服用葉酸及多種維生素,懷孕後接受高層次超音波檢查

這答案好像已經把etiology設定為:Folic acid deficiency
其它的etiology也包括了:Genetic factors
-->那麼D也應該是答案之一

Genetic factors — A genetic factor is suggested by the observations that
NTDs have a high concordance rate in monozygotic twins, are more frequent
among siblings, and are more common in females compared to males [9].
In addition, there is a high prevalence of karyotypic abnormalities among
fetuses with NTDs, especially in the presence of other congenital anomalies.
For example, a large study evaluating the frequency of chromosomal
abnormalities in pregnancies with fetal NTDs found these abnormalities in
6.5 percent of affected cases (4/167 fetuses with an isolated NTD and 9/33
fetuses with a NTD and associated anomalies) [10]. A second series reported
a similar rate (7 percent) of chromosomal abnormalities in fetuses with NTDs
[11]. Trisomy 18 was the most common aneuploidy in both series. These data
support the use of fetal karyotyping as an aid in diagnostic
evaluation and recurrence risk counseling.
