The tall stature, eunuchoid body proportions (long limbs with a short trunk), and gynecomastia in a male are typical findings in Klinefelter's syndrome. This syndrome is caused by the presence of an extra X chromosome (47,XXY) in males. Turner's syndrome (A) is characterized by short stature and ovarian failure. Fragile X syndrome (C) is an X-linked genetic disorder that can cause intellectual disability and behavioral problems. Marfan's syndrome (D) is a genetic disorder that affects the body's connective tissue and can cause abnormal tallness, long limbs, and other physical features. Duchenne-type muscular dystrophy (E) is an X-linked genetic disorder that affects the muscles and typically presents as progressive muscle weakness.
