Research on Alcohol Ingestion by Pregnant Women Has Shown That

Research on alcohol ingestion by pregnant women has shown that

A) mothers who were only social drinkers had babies who, for the most part, were unaffected by the alcohol consumption.
B) when mothers were given one ounce of vodka during their last trimester of pregnancy, no ill effects were seen in their fetus.
C) when pregnant mothers who were heavy drinkers ceased drinking during pregnancy, their babies tended to be longer and heavier at birth than mothers who continued drinking through their pregnancy.
D) infants whose mothers used both alcohol and tobacco during pregnancy were not found to be different in growth deficiencies than infants whose mothers had used only one or the other.
