option c. sperm are stored in the epididymis and leave the body through the urethra
The epididymis is a long, coiled tube that stores sperm and transports it from the testes. Although it bears some superficial resemblance to the testes, the epididymis differs in that it is smaller, and the tubes are larger and less densely packed. The head of the epididymis is where the sperm stores until it is ready to undergo maturation.
Male urethra connects urinary bladder to the penis. It is also more than a urinary duct, it also serves as a conduit for semen and sperm during sexual acts.
