Answer:
The options are
a. A lack of estradiol.
b. Moderate levels of estradiol during an early stage of development.
c. A high level of testosterone during an early stage of development.
d. A high level of testosterone during the late part of puberty.
The answer is b. Moderate levels of estradiol during an early stage of development.
Testosterone is a hormone which is responsible for the secondary sexual characteristics of a male while estradiol is the hormone responsible for the secondary sexual characteristics of a female.
This is why estradiol is the hormone responsible in female development regardless of the chromosomes
