What negative effects can arise from a mother's alcohol consumption during pregnancy?

The choice identifying a variety of mental and physical defects during a mother's alcohol consumption in pregnancy is accurate because it encompasses the full range of potential impacts known as Fetal Alcohol Spectrum Disorders (FASD). These effects can manifest as physical abnormalities, such as facial irregularities and growth deficiencies, as well as a variety of cognitive and behavioral challenges, such as learning disabilities, attention deficits, and difficulties with impulse control.

Research shows that alcohol can affect the developing fetus at different stages of pregnancy, leading to a spectrum of issues rather than a singular type of defect. These issues can vary greatly in severity and manifestation, highlighting the importance of understanding that alcohol consumption can lead to complex developmental challenges rather than just isolated physical or mental deficiencies. Thus, the correct answer reflects the comprehensive nature of the risks associated with alcohol intake during pregnancy.
