Which condition is characterized by multiple impacted extra teeth and the ability to approximate the shoulders together?

Explanation

Cleidocranial dysplasia is a genetic disorder marked by the presence of multiple impacted supernumerary teeth and the unusual ability to bring the shoulders close together due to underdeveloped or absent clavicles. Other options like Klinefelter syndrome, Trisomy 21, and Down syndrome do not typically present with these features.
