Toni Is About 10 Weeks Pregnant and Is Having Dinner

Toni is about 10 weeks pregnant and is having dinner with her sister, Kristy, who happens to be a psychology student. The sisters are sitting at a Mexican restaurant enjoying chips and salsa when the waitress asks them what they'd like to drink. Kristy orders a beer. Toni turns to Kristy and asks, "One beer isn't going to hurt, right?" Kristy is not only aware that Toni is pregnant, she is also knowledgeable of teratogens. What should Kristy say to Toni?

A) "Well, I guess since you are already 10 weeks along, then the beer shouldn't damage the fetus."
B) "There is not much alcohol in a beer, I wouldn't worry at all."
C) "The fetus is protected from the effects of alcohol because it can't cross the blood-brain barrier. You'll both be just fine."
D) "Well, Toni, the Surgeon General suggests you should not have ANY alcohol. Even a little can potentially cause fetal alcohol effects. Order a Sprite instead!"
