Correct Answer is C

Explanation

A. Prostate: The prostate gland contributes to the semen volume but only about 20-30%. It produces a fluid that nourishes sperm and helps transport them but is not the primary contributor to the total volume of semen.

B. Ductus Deferens: The ductus deferens (vas deferens) is a tube that transports sperm from the epididymis to the ejaculatory duct. It does not produce or contribute to the volume of semen.

C. Seminal Vesicle: The seminal vesicles contribute approximately 60% of the total semen volume. They secrete a fluid that is rich in fructose and other substances that provide energy for sperm and help in the formation of semen.
