Which of the following is derived from the Wolffian duct?

An appendix of the epididymis is a developmental remnant of the mesonephric duct (Wolffian duct) which can be found in the head of the epididymis. In the female, in the absence of testosterone, the Wolffian duct regresses. However, inclusions may persist resulting in the epoophoron and Skene's glands. Where a remnant exists lateral to the wall of the vagina a Ganer's duct or Ganer's cyst may form. In males, the Wolffian duct develops into the rete testis, the efferent ducts, the epididymis, the ductus deferens and the seminal vesicles. The prostate is formed separately from the urogenital sinus. In both the male and the female the Wolffian duct develops into the trigone of the urinary bladder. Ref: Gray's 39e/p-1289
