Your Roommate's Sister-In-Law Is Pregnant and Is Trying to Do

Your roommate's sister-in-law is pregnant and is trying to do all that she can to protect her foetus and to make sure that her foetus develops well. She does not like to have any loud music on and even does not talk very loudly for fear that her foetus will be harmed. What would you tell her?

A) That her foetus will not be adversely affected and that studies have discovered that foetuses actually prefer their mothers' voices. So, she should talk as much as she likes.
B) That she is correct; loud music is readily transmitted through the amniotic fluid and will cause damage to the foetus's cochlea.
C) That she should play Mozart really loudly. Foetuses who listen to Mozart are more intelligent than those who do not listen to Mozart.
D) Research has shown that foetuses love country music.
