Answer:
The correct answer is A.
Explanation:
Androgen insensivity syndrome (AIS) is a genetic autosomal recessive disease linked to X chromosome.
During development, an 46XY embryo with AIS cannot process the androgens produced by the testes, but they do respond to other hormones, therefore the testes form and function during embryonic development.
Testes produce Müllerian inhibiting hormone, which stops the development of uterus, fallopian tubes and cervix.
But the Wolffian ducts aren’t able to respond to androgens secreted by the testes, so as a result, they don’t turn into prostate gland, spermatic ducts, ejaculatory ducts or seminal vesicles.
External genitalia develop as a normal 46XX female fetus, because they don’t respond to testosterone and dihydrotestosterone (androgens )
