C Correct answer
Explanation

Sperm production (spermatogenesis) requires a temperature 2-3°C lower than normal body temperature (37°C). The scrotum's external location maintains this cooler temperature, which is optimal for sperm development and viability. Higher temperatures can impair sperm production.
