The correct option is
B Vas deferens and vasa efferentia
The male sex accessory ducts include rete testis, vasa efferentia, epididymis and vas deferens. The seminiferous tubules of testis open into Vasa efferentia through rete testis. The vasa efferentia leave the testis and open into epididymis located along the posterior surface of each testis. The epididymis leads to vas deferens that ascends to the abdomen and loops over the urinary bladder.
so, the correct option is 'Vas deferens and vasa efferentia'.
