Sex steroids play important roles in inducing the body changes known as primary sex characteristics and secondary sex characteristics.
The development of both primary and secondary sexual characteristics is controlled by sex hormones after the initial fetal stage where the presence or absence of the Y-chromosome and/or the SRY gene determine development.
In many contexts, the two main classes of sex steroids are androgens and estrogens, of which the most important human derivatives are testosterone and estradiol, respectively. Other contexts will include progestagen as a third class of sex steroids, distinct from androgens and estrogens. Progesterone is the most important and only naturally-occurring human progestagen. In general, androgens are considered "male sex hormones", since they have masculinizing effects, while estrogens and progestagens are considered "female sex hormones"[1] although all types are present in each gender, albeit at different levels.

I would go with B. With the absence or minimal production of androgens, all babies would be female. Thus I am assuming that the estrogens influence this development.
I hope this helps. Thanks for asking.
