B testes begin to differentiate

Answered by bobpursley
It turns out brain development in the male is turned on before testes are differentiated, there are a number of studies on male/female development differences. However, I am not certain the male brain develops more rapidly, it just develops differently. Given that, B is the best answer. IMO, trick question.
