Verified by Experts

The correct Answer is:
B
In mammals, scrotal sacs (containing testes) act as thermoregulator, maintaining the temperature of the testes `2^(@)C` 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.
