Explanation:
Detailed explanation-1: -Testes are present outside the human body, in scrotal sacs because the optimum temperature required for the production of sperms is 2-3 degrees less than the body temperature. The surface area of the scrotal bags changes accordingly to them keeps the temperature inside constant.
Detailed explanation-2: -Thus, the correct answer is ‘2oC below body temperature’.
