**Core Concept**
Prenatal exposure to cigarette smoke can have detrimental effects on fetal development, leading to various congenital anomalies and increased risk of perinatal complications. This is due to the transfer of nicotine and other harmful substances from the mother's bloodstream to the fetus through the placenta.

**Why the Correct Answer is Right**
The nicotine in cigarette smoke crosses the placental barrier and can affect fetal development by altering the expression of genes involved in cell growth and differentiation. This can lead to an increased risk of birth defects, such as cleft palate, heart defects, and growth restriction. Additionally, maternal smoking during pregnancy has been associated with an increased risk of sudden infant death syndrome (SIDS) and other perinatal complications.
