Which characteristic is commonly associated with Down syndrome?

• A. Advanced language development
• B. Tall stature
• C. Hyperactivity
• D. Hypotonia and mild-to-moderate intellectual disability

Answer: (D)

Down syndrome commonly presents with hypotonia (low muscle tone) in infancy and with mild-to-moderate intellectual disability. This combination captures the typical motor and cognitive profile clinicians look for, reflecting the common developmental pattern seen in many individuals with the condition. Other listed features don’t align with Down syndrome—for example, language development is usually delayed rather than advanced, stature tends to be shorter rather than tall, and hyperactivity is not a defining, defining feature of the syndrome.
