The correct option is D Vas deferens
The epididymis is divided into three areas as caput (head), corpus (body) and cauda (tail). Spermatozoa recovered from cauda epididymis are fertile and are capable of motility. The epididymis then leads to vas deferens.
Vas deferens is the tube that arises from cauda epididymis and reaches upto seminal vesicles.
Therefore, the correct answer is option B.
