Vasa efferentia are the ductules leading from
Epididymis to urethra
Testicular lobules to rete testis
Rete testis to vas deferens
Vas deferens to epididymis
The male gametes are formed in the seminiferous tubules of testis, the sperms from testis are carried to the female reproductive tract by the help of accessory ducts and follows the following path:
Seminiferous tubules → Rete testis → Vasa efferentia → epididymis → Vas deferens → urethra and from urethra to the external genitalia penis.
Thus, the correct answer is c.
