Which hormone helps develop secondary sexual characters in girls during adolescence?

Answer and explanation

Correct answer: Estrogen

The governing concept is endocrine control of puberty. Estrogen is mainly secreted by the ovaries and helps produce female secondary sexual characteristics during adolescence, such as breast development and changes in body shape. Therefore option A is correct. Testosterone is more strongly associated with male secondary sexual characteristics, adrenaline supports emergency responses, and auxin regulates growth responses in plants rather than humans.
