The given figure shows a diagrammatic stretch of a portion of human male reproductive system. Identify the parts labelled as A, B, C and D and select the correct option.

The correct option is A A-Vas deferens, B-Seminal vesicle, C-Prostate, D- Urethra
A-Vas deferens = The vas deferens is a long, muscular tube that travels from the epididymis into the pelvic cavity, to just behind the bladder.

B-Seminal vesicle = The seminal vesicles are a pair of glands found in the male pelvis, which function to produce many of the constituent ingredients of semen.

C-Prostate = The prostate is a part of the male reproductive system, which includes the penis, prostate, seminal vesicles, and testicles. The prostate is located just below the bladder and in front of the rectum.

D- Urethra = The urethra is the tube that carries urine from the bladder to outside of body. In males, it has the additional function of expelling (ejaculating) semen.

Hence, the correct answer is A-Vas deferens, B-Seminal vesicle, C-Prostate, D-Urethra.
