The correct sequence of organs in the male reproductive system for transport of sperms is (a) testis → vas deferens → urethra.
Explanation:
Testis: This is where sperm is produced.
Vas deferens: A tube that carries sperm from the testis to the ejaculatory duct.
Urethra: The final passageway through which sperm is expelled from the body during ejaculation.
Why other options are incorrect:
(b) testis → ureter → urethra: The ureter is a part of the urinary system and is not involved in sperm transport.
(c) testis → urethra → ureter: Sperm does not travel directly from the testis to the urethra.
(d) testis → vas deferens → ureter: The sperm does not travel through the ureter, which is for urine transport.
