Vas efferentia opens into which of the following structures?
Epididymis
Vas deferns
Seminal vesicles
Rete testes
The male sex accessory ducts include rete testis, vasa efferentia, epididymis and vas deferens.
The seminiferous tubules of the testis open into the vasa efferentia through rete testis.
The vasa efferentia leave the testis and open into epididymis located along the posterior surface of each testis.
Hence option A is correct.
