  The vas deferens receives duct from the seminal vesicle and opens into urethra as (a) epididymis   (b) ejaculatory duct        (c) efferent ductule        (d) ureter

Answer:

                  (b)The vas deferens is a continuation of the cauda epididymis (tail part of epididymis). Itis about 40 cm long and slightly coiled at first but becomes straight as H enters the abdominal cavity through the inguinal canal .Here, it passes over the urinary bladder, curves round the ureter and joins a duct fromseminal vesicle and opens into urethra as the ejaculatory duct. These ducts store and transport the sperms from the testis to the outside through urethra.
