The correct answer is Option (1) → (D), (B), (A), (C)
Sperms form in the seminiferous tubules of the testicular lobules and then pass through the ducts in this order.
(D) Vasa efferentia — first. The tubules open through the rete testis into the vasa efferentia, which carry the sperms out of the testis.
(B) Vas deferens — second. After the epididymis, sperms pass into the vas deferens, which goes up into the abdomen and joins the duct of the seminal vesicle.
(A) Urethra — third. The ejaculatory duct opens into the urethra, the common passage through the penis.
(C) Urethral meatus — last. It is the external opening of the urethra.
