Verified step by step guidance

1. Understand the context: Fetal Alcohol Syndrome (FAS) is a condition caused by alcohol exposure during pregnancy. It can lead to physical, behavioral, and cognitive abnormalities in the developing fetus.
2. Review the symptoms of FAS: Common symptoms include growth deficiencies, central nervous system abnormalities, and distinctive facial features such as a smooth philtrum (the groove between the nose and upper lip).
3. Eliminate incorrect options: Accelerated growth rate, enhanced immune response, and increased muscle mass are not associated with FAS. These options do not align with the known symptoms of the condition.
4. Focus on the correct option: Distinctive facial features, such as a smooth philtrum, are a hallmark symptom of FAS and are often used as a diagnostic criterion.
5. Conclude: The correct answer is 'Distinctive facial features such as a smooth philtrum,' as it directly describes a symptom of Fetal Alcohol Syndrome.
