The correct option is C epididymis
Stereo cilia are found in the male reproductive tract and are thought to facilitate absorption in the epididymis and vas deferens. Stereo cilia are actin-based protrusions that are also present on auditory and vestibular sensory cells. They are required for hearing and balance. They convert physical force from sound, head movement or gravity into an electrical signal, a process that is called mechanoelectrical transduction. The ureter and uterus have cilia which provide protection and helps in movement.
