The correct answer is A. Women have been encouraged to avoid alcohol during pregnancy.
Explanation
In recent years there have been several studies on the effects of alcohol consumption by a pregnant mother on her child. First, it has been found that there is no acceptable minimum amount of consumption of any type of alcohol during pregnancy in any of its stages. Additionally, studies on the subject reached conclusions such as that the pregnant mother can affect the baby if she consumes alcoholic beverages since the liquor passes from the mother to the baby through the umbilical cord, likewise the mother not only risks affecting her child causing disabilities of various kinds but may miscarry it. So the correct answer is A. Women have been encouraged to avoid alcohol during pregnancy.
