Solution

The correct option is A Spermatogenesis
In mammals, scrotal sacs (containing testes) act as thermoregulator, maintaining the temperature of the testes 2oC lower than that of the body. This temperature is required for the spermatogenesis to occur otherwise, the sperms could be destroyed by high temperature, resulting in sterility.
