B) Turner syndrome.
C) complete androgen insensitivity syndrome.
D) Klinefelter's syndrome.

Individuals who externally look like any other woman but have a genetic composition of XY are said to have complete androgen insensitivity syndrome (CAIS). This is a genetic condition in which the body cannot respond to male hormones (androgens). As a result, individuals with CAIS develop typically female physical characteristics, but they have undescended or partially descended testes instead of ovaries. They typically identify as female and have a female gender identity.
