Solution
The correct option is C Both A and B
The testes produce the sperms by the process of spermatogenesis in the seminiferous tubule. They descend into the scrotum, a skin-covered sac suspended from the groin. The scrotum serves as a cooling unit, maintaining sperm below body temperature. Having descended testes is a derived characteristic within mammals. Descended scrotal testes are found in horses, pigs, camels, and carnivore. In elephants, testes descend only during the breeding season. In shrew also testes are retained within the abdominal cavity of males.
So, the correct answer is option C.
