D)ejaculatory duct
E)seminal vesicle

Accepted Answer

The vas deferens, which transports sperm from the testes to the urethra, is the only structure that is cut during a vasectomy. The other structures listed all contribute to the production or composition of semen, but the vas deferens is the only structure that is permanently affected by the procedure. Of the options given, the seminiferous tubules are most closely associated with sperm production.
