(D) Klinefelter's syndrome is a genetic disorder caused by the presence of an additional copy of the $X$-chromosome,resulting in a karyotype of $47, XXY$.Statement $B$ is correct because individuals with this syndrome exhibit overall masculine development,but they also show some feminine characteristics (such as gynaecomastia).Statement $E$ is correct because these individuals are sterile.Statements $A$,$C$,and $D$ are incorrect because they describe features associated with Down's syndrome,not Klinefelter's syndrome.
