Which of the following statements correctly describes a hormone or its function as presented in the text?
A: Mineralocorticoids primarily regulate salt and water balance, and aldosterone is an example.
B: Testosterone is the main androgen produced by the ovaries, primarily functioning in female embryonic development.
C: Estrogens, like progesterone, are primarily responsible for promoting male secondary sex characteristics.
D: Gonadotropin secretion is directly controlled by the anterior pituitary gland, independent of the hypothalamus.
