Answer 1

The correct option is C Testosterone from testes and estrogen from ovary

Testes are a pair of glands which are present only in males (men). They secrete male sex hormone called testosterone. The function of testosterone hormone is to control the development of male sex organs and secondary sexual characteristics in men such as deeper voice, moustache, beard, etc.

Ovaries are a pair of glands which are present only in females (women). They secrete female sex hormones called oestrogen and progesterone. The function of oestrogen hormone is to control the development of female sex organ and female features such as feminine voice, soft skin and mammary glands.
