Answer:
epididymis 
ductus deferens
ampulla of ductus deferens
seminal gland
ejaculatory duct
urethra
Explanation:
Epididymis is a tube that connects the back side of the testicles to the vas deferens (ductus deferens). The vas deferens is the connecting link between epididymis and urinary tract/urethra and is responsible for transporting sperm to the urethra. Seminal vesicles are small glands that lie above the prostate gland and make up more than 50% of the total semen. Seminal vesicles are connected to the vas deferens through ejaculatory duct. This duct empties sperm and semen into the urethra
Hence, the correct order is
epididymis 
ductus deferens
ampulla of ductus deferens
seminal gland
ejaculatory duct
urethra
