The description matches Turner's syndrome, which is due to the absence or partial absence of one X chromosome in females. This results in short stature, infertility, and difficulties in math and science. Klinefelter's syndrome (A) is due to an extra X chromosome in males, resulting in infertility and other physical and cognitive effects. Fragile X syndrome (C) is a genetic disorder that results in intellectual disability, delayed speech, and social and emotional impairments. Tay-Sachs disease (D) is a rare genetic disorder that results in the progressive destruction of nerve cells in the brain and spinal cord.
