Pregnant women who smoke have an increased risk of
a. miscarriage.
b. ear infections.
c. lower respiratory infections.
d. sudden infant death syndrome.

The answer is letter A. 

Pregnant women are discouraged to smoke while pregnant. This can cause miscarriage because of the toxic chemicals that cigarettes bring and are readily absorbed by the fetus when a mother smokes. Not only will it lead to a possible miscarriage, if the baby does survive, he/she might end up with physical abnormalities or mental disorders. This is the reason why mothers should be very careful about the choices they make during pregnancy because the life of a younger being is also at stake.
