Answer:
The ovaries and the testes
Step-by-step explanation:
The organs responsible for the development of secondary sex characteristics would be the ovaries and the testes.
Both ovary and testes are associated with the sex organs in the body and are responsible for the synthesis of hormones such as androgen and estrogen. While the latter (estrogen) is produced by the ovary, the former (androgen) is produced by the testes.
More specifically, both androgen and estrogen are hormones responsible for the growth of hairs in areas such as the armpit and the pubic regions of the body.
The correct options are the ovaries and the testes.
