Solution

The correct option is A Rete testis, vasa efferentia, epididymis and vas deferens
The male accessory ducts are rete testis, vasa efferentia, epididymis, and vas deferens. The function of rete testis is to store sperms produced by seminiferous tubules; while vasa efferentia helps to transport sperms from rete testis to epididymis. Epididymis provides nutrition for the maturation of sperms and vas deferens conduct the transport of sperms from the epididymis to urethra.
So, the correct answer is option B, Rete testis, vasa efferentia, epididymis and vas deferens.
