Which of the following karyotypes is least likely to be associated with a patient presenting with amenorrhea, short stature, and sparse pubic hair?

Explanation

Patients exhibiting amenorrhea, short stature, and reduced pubic hair are commonly linked to chromosomal abnormalities such as 45,X (Turner syndrome) or other sex chromosome variations. The 47,XXY karyotype (Klinefelter syndrome) typically presents differently and is less likely to show these features. Therefore, 47,XXY is the exception among the listed options.
