Question

what is a known health risk to a baby if the mother smokes during pregnancy?
○ premature birth
○ sudden infant death syndrome
○ genetic birth defects
○ underdeveloped lungs

Explanation:

Smoking during pregnancy can lead to various health risks for the baby. Premature birth is a well - known risk. Nicotine and other harmful substances in cigarettes can restrict blood flow to the placenta, which may cause the baby to be born before 37 weeks of gestation. Sudden infant death syndrome (SIDS) is also associated with maternal smoking during pregnancy, but it is more of a post - birth risk factor. Genetic birth defects are mainly caused by genetic mutations or chromosomal abnormalities, not directly by smoking (although smoking can have epigenetic effects, it is not the primary cause of genetic birth defects in the traditional sense). Underdeveloped lungs can be a consequence of premature birth, but the most direct and well - established known risk among the options given is premature birth.

Answer:

premature birth
