• B. Estrogen from adrenal gland and testosterone from pituitary gland

• D. Testosterone from thyroid gland and estrogen from pituitary gland

Answer 1

Answer: (C)

Testosterone from testes and estrogen from ovary

In a child, dramatic physical and mental changes are observed during their adolescence period. These changes occur because of puberty. The key role for this is played by the sex hormones that are steroids. In humans, the principal male hormone is testosterone, which is produced by testes. This hormone promotes the development of secondary sexual characteristics. In females, the hormone estrogen produced by the ovary is responsible for the development of secondary sexual characters.

So, the correct answer is option C.
