Option 1: Spermatogenesis is the process of sperm production, which primarily occurs in the testes. The epididymis, vas deferens, seminal vesicles, and prostate do not play a direct role in spermatogenesis. Therefore, option 1 is incorrect.

Option 2: The epididymis, vas deferens, seminal vesicles, and prostate all contribute to the maturation and motility of sperm. The epididymis is responsible for the maturation of sperm, giving them the ability to swim and fertilize an egg. The vas deferens transports mature sperm from the epididymis to the urethra. The seminal vesicles and prostate produce seminal fluid, which nourishes and maintains the motility of sperm. Therefore, option 2 is correct.

Option 3: Option 3 includes both spermatogenesis and motility of sperm. However, spermatogenesis primarily occurs in the testes, and the epididymis, vas deferens, seminal vesicles, and prostate do not play a direct role in this process. Therefore, option 3 is incorrect.

Option 4: Motility of sperm is indeed one of the functions of the epididymis, vas deferens, seminal ves
