Correct Answer: (d) (iii) and (iv)

Explanation: The function of testes (present in males) at puberty includes the formation of germ cells and the secretion of male sex hormones that is testosterone.

Estrogen and progesterone are female sex hormones and not secreted as a function of testes.

The placenta develops in the female after the implantation of an embryo in the uterus.
